At the beginning, as a mold company, we do not recommend buying Pet Bottle Preform at a low price, because good molds are definitely not sold at low prices. So we are talking about buying molds to buy the right mold for your company?
We need to buy a mold that suits us. Before the inquiry, the buyer should have a good understanding of their own products and production conditions. You should know the output of the product, the weather of the recycled product, the appearance of the product, the size of the machine to be prepared, and the spare parts in the surrounding market. In this way, the mold manufacturer can choose different mold steels, injection types, cavity numbers, measurement standards and other accessories according to the customer’s situation, all of which can help us provide the right mold for the customer.
When we check the mold test, we should pay attention to the mold cooling, noise, each moving part, and ensure that the injection is under normal pressure. It’s best to let the mold maker make the product for you. You can pay for the extra cost to buy the product; this way, we can see if the mold works well and we may find some problems. Even if we find any problems, the molds are still in the factory and they can be improved. This will be much better than the problem you found in the factory.
If you are in need of a 5-Gallon Pet Preform mold purchase or a problem, please come to contact Jilian mold, I believe we can provide you with a perfect solution.
Jilian Plastics is a China pet preform manufacturers. We produce different plastic molds, such as plastic bottles, plastic cups and related plastic manufacturing equipment. For plastic molds, we also have OEM after-sales market. Usually we use the following steps to make a plastic shock absorber mold:
– Product analysis and mold process analysis, as well as new mold technology conference
The team of JL Plastics engineers inspected the product and, if necessary, we will make a rapid prototyping sample to check for matching with other parts. In addition, mold flow analysis is necessary before the mold structure is fixed. In this way, we can anticipate any defects in the design and check the appropriate injection system. We will hold a new mold technology meeting to discuss mold structure, especially mold injection system, ejection moving parts, cooling channels and time control, mold tolerance control and so on. ,
-Mold precision machining and mold CMM control
For shock absorber molds, we will use a two-step process from roughing to precision machining. For precision tools, we use a high-speed CNC machine tool, Fidia 3 + 2 CNC tool center for tool processing. Jilian mold will check the mold parts after the CMM measuring machine completes the machining process to check whether the mold tolerance is qualified according to the mold drawing. We can provide customers with CMM measurement reports to check mold parts.
– Mold testing and sample control
After the Pet Preform Mould test, a detailed sample inspection report will be provided to our customer for inspection along with the sample. Sample production will maintain the condition of the sample under different conditions.

Pet Bottle Preform manufacturers favor custom plastic injection molding for good reason. This molding method has various advantages. It involves feeding plastic material into a heated bucket where they are mixed and transferred to the mold cavity. This is where the final product forms and hardens. This is not the only way to process plastics, but it quickly became the most preferred method. Here are some of the benefits of custom plastic molding and some of the shortcomings.
Custom plastic molding is extremely fast. This is one of the main reasons why it is so popular as a long-term production technology. Although the exact speed of the process depends on the nature of the mold, it usually takes 15 to 30 seconds to cycle between cycles.
It creates high-strength components
Those who need superior parts use plastic injection molding. Custom plastic molding allows for the addition of filler to the part during processing. These fillers reduce the density of the liquid plastic and enhance the strength of the final product.

Custom plastic molding is an automated process. Almost all work is done by robots, computers and machines. Plastic injection molding equipment operates with self-sinking technology that allows for uninterrupted operation with minimal supervision. One can control each of these processes.
The end result is that overhead costs are reduced due to a significant drop in labor and manufacturing costs. Post-production work is limited because the parts are very precise, sturdy, and completed from generation to generation.
Custom plastic injection molding is very precise. This process produces almost all types of plastic parts. Despite some design limitations, the mold was manufactured such that the final product was within 0.0005 inches of the expected result.
The plastic injection molding process is very flexible. The type of material can be easily changed. Even the color to be produced by plastic parts can be changed without a lot of time or effort. Regardless of the specific size of the part being produced, the flexibility of this process is almost limitless.
These injection molds are exposed to incredible high pressures, making the molds pressed tighter than other forming methods. The use of Computer Aided Manufacturing (CAM) and Computer Aided Design (CAD) allows even the smallest nuances and the most complex designs to be perfectly implemented in the creation of parts. It is even possible to experience very tight tolerances of 0.001 or greater.

1) Understand the difference between colorants: just like the base resin, not all resin colorants are the same. When used with different resins, different quality colorants can produce different results, resulting in an imperfect appearance or worse damage to the finished part of the Pet Preform Mould. Here are some colorant qualities to watch out for:
Carrier Material: The “carrier” of the colorant is a substance that binds or holds the colorant together. This is an irrelevant material because it has no other use; however, it can play an important role in the appearance and quality of the finished product. See the following points for more information.
Mixing ratio: Depending on the colorant, carrier and base resin, the initial mixture should have a certain ratio – typically 3 – 5 pounds of colorant per 100 pounds of base resin. It is also important to note the percentage of carrier material in the colorant – this material typically accounts for 1% – 3 % of the finished product. If this ratio does not exist, you may have appearance problems like vortexes, streaks, and bumps. Improper mixing can also create unexpected performance problems in the finished product.
Colorant Material: Just like the carrier material, it is important to ensure that the colorant material is compatible with the base resin.
2) Resin compatibility: As mentioned above, it is important to discuss this issue specifically to further explore why compatibility between the resin, colorant and carrier is so important.
Resins are typically formulated for a specific set of performance attributes, usually at the molecular level. The introduction of foreign elements into the resin mixture – in this case, the two elements, the colorant and the carrier – can affect the desired properties, especially when these materials react adversely to each other.
For example, incompatible colorant materials can alter the upper and lower temperature tolerances of the resin. They change the flexibility and hardness of the resin and allow it to react differently to moisture and humidity. Incompatible resin and colorant blends are easier to dry and more prone to flaking and cracking – at best it’s a cosmetic problem and, worse, an imminent danger.
In addition to the reaction between the materials, the quality of the physical mixture may also vary, usually in the same manner as described above. Basically, the base resin is being diluted by the colorant, so it is important to either plan and adjust the formulation for this purpose, or to ensure that the colorant is compatible with the resin and, when used together, will adhere to the desired results.
3) Certification or other grading purposes: As a more specific example, let us detail the use in the case of certification or grading, such as medical or food. Other certifications such as quality, safety and green issues can also fall under this umbrella.
As mentioned above, in addition to the colorant, the carrier itself can account for 1% – 3 % of your finished product. The nature of this amount of material can determine whether a safety certification is obtained – a process that can take years. It is also important to choose a supplier to help you consider the medical or food grade quality of the colorant mixture and conduct research to ensure that your product still meets these parameters if needed.
4) Pantone matching: The last point to consider is the pure aesthetics of adding colorants to injection molded resin products: What color do you need? Many stores will offer you “blue”, “yellow” and other items. However, if you have a specific look, please note that Pantone matches the colorant with a precision of up to 1%. This is an option in more experienced facilities. We choose Jianlian Mold, we are very professional China Pet Bottle manufacturers, we can provide you with different color products to ensure that you meet your expectations.
There are different issues to be aware of when purchasing a Pet Bottle Preform mold to minimize production problems associated with the use of the mold. Potential production problems with used molds include poor part quality, slow cycle times, low molding ratios, and machine downtime due to poor part discharge.
Molding machine damage
Another major problem is that the molding machine may be damaged due to the molded parts used. Used plastic molds are generally in poor condition, which can result in broken tie bars, plate wear, and even breakage of the toggle pin.
Step-by-step guide to buying a mold
In order to get the most out of the used plastic injection molds, you need to ask some questions before buying them.
Ask to see the operation of the mold or request a sample. This is the only way you can accurately understand cycle time and quality.
Samples are taken from all caves. The sample was weighed and its thickness was measured. This information will give you a more accurate picture of the mold condition. Any big changes in the cavity, then you know that you should not buy these.
If you want to get a satisfying and affordable pet preform, choosing a reliable pet preform manufacturers is the most important. Today, we recommend the Gianlian mold. We have many years of experience in the field of plastic molds. We will never let you down.
Hot runner Pet Bottle Mould
Hot runner molds consist of two broad categories: internal and external heating systems. External heating systems are more suitable for polymers because they are susceptible to thermal forms. On the other hand, the internal heating system promotes better flow control. These types of plastic molds consist of two plates that are heated using a manifold system that drives the dissolved plastic to the nozzle. These nozzles fill the part cavity. Unlike cold runner molds, hot runner molds completely remove runners, so they have no effect during cycle times.
Insulated runners are an improvement to this system. The insulation keeps the plastic in a molten state, not heat. It can only accept small amounts of plastic, especially semi-crystalline polymers, because of its low thermal conductivity.
Eradicate runners and possible waste
Can accommodate larger parts
Can speed up cycle time
No robots are needed to eliminate runners
Hard to change color
Production can be expensive
Higher maintenance costs
Thermally sensitive materials are not suitable
A professional china pet preform manufacturers, Jilian Mold can help you determine the right injection molding system for your project. They should be fully aware of all types of plastic processing. They can also help you find used plastic molds or used injection molds, or they can give you advice if they are cost effective.
Here are some things you should know as a custom Pet Bottle Preform that product developers should know. Are you looking for a cost-effective way? The process that doesn’t force you to spend a lot of money on producing a lot of parts is custom injection molding. However, if you are considering return on investment (ROI), which process you decide to use to make a large number of parts should depend on this, as the purchase of plastic injection molds involves an initial investment. Here are some other things you should know about custom injection molding.
Think about the number of parts you need to produce each year. Will your needs reach tens of thousands or hundreds of thousands? If so, then this process is not for you. Look for other programs, such as polymer casting, manufacturing, or vacuum/thermoforming (but your final decision will depend on the geometry of the part or part).
If you believe that the number of parts you produce will make your initial investment in custom plastic injection molds (even old plastic injection molds) worthwhile, you must also consider the shape of the part when choosing which molding process to use. .
If you don’t know or want to know more about the different thinking processes and the shapes or geometries that fit them, continue reading the following:
Custom Injection Molding – The wall thickness of the part is relatively constant (but generally no more than 1 / 8″). There is no internal void.
Rotational Molding – This method is used to produce larger or larger parts with empty spaces (or so-called internal voids) inside. Rotational molding is a slow and efficient process of making small, large parts for the manufacture of waste bins, gas canisters, tanks, hulls and other items.
Blow Molding – To help you understand blow molding, imagine a balloon swinging in a cavity. It is injected into the air and eventually forms the shape of the cavity. This process is used to make bottles, insulating glass, kettles and other things. It can be small, but there is an empty space inside.
Vacuum (hot) forming – this is somewhat similar to custom or plastic injection molding. It takes advantage of a piece of heated plastic and then vacuums it to form a shape that is then cooled to produce the shape you want. It is used for packaging trays, lids, clamshells and other such as instrument panels, plastic trays and refrigerator liners.
The information provided above will give you an idea of using the best molding process. No matter which method you think you need, it’s always important to start with calculations, especially because you want to know the return on investment so you can determine which method is best for your budget and pet preform manufacturers. As a product developer, you should consider a schedule of up to two to three years before recouping funds for custom injection molding.
When a company decided to move to a plastic injection molding machine, this was not a small task. Companies that need tool repositioning or Pet Preform Mould transfer are often cautious about this process for several reasons. Some companies are trying to avoid this situation altogether, and even choose to build a new tool in the same factory instead of shipping it to a new factory. With the right processes and safeguards, tool transfer is a completely viable option.
When the tool is repositioned
Moldmakers are often required to perform “die takeovers” or tool transfers. Essentially, this process is when you transfer the mold to the mold factory for inspection and injection mold testing, so you can get your project and production capacity back on track.
Communication is the key to transfer
Mold transfer requires planning, communication, and investment in advance to achieve project goals and expectations. Injection molding machines must fully understand the ultimate goal. The required information and actions did not leave any space beyond the full cooperation and disclosure of both parties. Choosing a reliable China Pet Bottle manufacturer can provide more convenience and convenience for your mold design and manufacturing.
Domestic automatic pet blowing machine have long relied on high prices, and the small and medium-sized enterprises in the industry basically rewrite the original hand-blowing bottles in history.
Hollow Blow Molding Machine is widely used in milk beverages, cold drinks, medicine and health care products, cosmetics and other industries. However, for a long time, there is only a simple production of manual clamping devices in China. Most SMEs are manually clamped in the original blow molding machine. Blowing machines, molds and bottles require a large number of skilled workers, with high cost, low output and low qualification rate. Some large companies have spent a sum of money on imported injection molding machines. The molds are expensive, and they are generally used for mass production and less replacement products. They cannot meet the current domestic demand for bottle size changes.
The fully automatic PET bottle machine has Chinese characteristics. It combines electric, pneumatic and mechanical transmission, and has the characteristics of advanced performance, simple and practical, simple operation and low cost. The first user automatically rotates the plastic bottle. In the past, the manual clamping device produced a bottle of 100 ml “pops” as an example. One machine has only one ordinary operator, which is reduced by 4 people; class production It reached 23,000 people, an increase of 13,000; more than 98% of qualified products. In addition, there have been significant changes in raw material savings, customer satisfaction, employee labor intensity, and weight deviation, and the overall economic benefits have doubled in the past.
Experts in the industry believe that the development of automatic PET bottle machine has been successful and has achieved large-scale production. This is a new breakthrough in domestic packaging machinery and equipment in recent years. The unit price of this equipment is only 1 / 20 of imported equipment, and also It is suitable for the change of bottle type of Pet Bottle Preform, which is conducive to the popularization of domestic packaging and blowing the bottle into mechanized production as soon as possible.
