Heat Treatment Process Of Pet Preform Mould

According to different cooling media, vacuum quenching can be divided into vacuum oil quenching, vacuum gas quenching, vacuum quenching and vacuum nitric acid isothermal quenching. Vacuum oil quenching, vacuum gas quenching and vacuum tempering are mainly used for vacuum heat treatment of molds. In order to maintain the excellent characteristics of vacuum heating of workpieces (such as molds), the ions and development of the coolant and cooling process are very important.
Vacuum heat treatment technology is a new type of heat treatment technology developed in recent years. It has the characteristics that are urgently needed for the manufacture of Pet Preform Mould, such as preventing heating oxidation and decarburization, vacuum degassing or degassing, and eliminating hydrogen embrittlement, thereby improving the plasticity, toughness and fatigue strength of materials (parts). The vacuum heating is slow, the temperature difference between the inside and the outside is small, and the small deformation generated during the vacuum heat treatment.
For heat treatment after no longer processing the surface of the mold, it is possible to improve the surface quality of mechanical properties such as fatigue properties, surface brightness and corrosion after vacuum quenching as much as possible, especially vacuum quenching the workpiece (mold).
The successful development and application of computer simulation technology, including tissue simulation and performance prediction technology, has made intelligent heat treatment of molds possible. Due to the small batch (even single piece) of mold production, the characteristics of many varieties, as well as the heat treatment performance requirements are high, and the characteristics of waste products are not allowed, making the mold for intelligent heat treatment necessary. The intelligent heat treatment of the mold includes: clearing the mold structure, material and heat treatment performance, the temperature field and stress field distribution of the mold heating process, computer simulation of the temperature field, phase transformation process and stress field distribution during the mold cooling process, computer simulation heating and cooling process, Simulate the quenching process, develop heat treatment equipment, and automate control technology.
Developed countries abroad, such as the United States, Japan, etc. In the vacuum high-pressure gas quenching, technology research and development has been carried out in this field, mainly for molds. In the field of China Pet Bottle, Jilian Plastics is an expert in this field. It can perfectly solve the problems encountered in this process and is a good partner on your mold manufacturing road.

Injection Molding To Make A Variety Of Pet Preform Mold

Plastic injection molding is perhaps the most common process for making plastic products. Why do China Plastic Handle Manufacturers prefer this program to other companies? It has a wide range of features. It can be used to make parts with undercuts, springs, hinges, holes and threads. Whether the desired product needs to be solid, foamed, plated, hot stamped, textured, rigid, polished, colored or transparent, simple or complex, reinforced or filled, small or large, thick or thin, does not matter.
There are so many things you can do with injection molding, and we will show you how the magic in the factory happens.
Plastic injection molding process
Injection molding machines vary in size and shape. It has a desk-sized unit, even as big as a house! Even though the machines are actually different, all machines contain two systems: the injection system and the clamping system.
There are two types of injection systems: a common reciprocating screw and a two-stage screw. The components of the reciprocating screw system are a hopper, a reciprocating screw, a syringe, a hydraulic motor, and a syringe.
The injection system begins to work when the resin is placed in the hopper manually or under vacuum. The resin melts to its proper fluidity or viscosity. The molten plastic is rotated into the inside of the syringe by the rotation of the reciprocating screw driven by the hydraulic motor. The molten plastic is then towed to the nozzle portion of the syringe and then injected into the mold. After the plastic cools, the machine will eject the plastic and the cycle begins again.
Wonderful plastic
As mentioned earlier, the injection molding machine can manufacture almost any type of plastic article. Jilian Plastics uses injection molding to produce a wide range of Pet Preform molds and products that meet the needs of customers all over the world and have a certain position in the international market.

China Plastic Handle Manufacturers First Use Injection Molding Technology

Manufacturers prefer plastics because of the efficiency, versatility and strength of plastics. It can be molded into a variety of shapes and sizes using simple or complex techniques. Because of this, plastic injection molding has become the most popular product in current practice.
Injection molding is not avant-garde. In fact, this manufacturing process has been in use since the late 19th century. It is the introduction of polymers that have brought the biggest changes to the industry. If you still want to know why it is the preferred process for China Plastic Handle Manufacturers, here are three reasons.
Injection molding has a prominent effect.
Compared to other molding processes, the use of polymers is surprisingly fast and more parts can be fabricated in one mold. Due to high productivity, the entire manufacturing process is very cost effective.
The exact characteristics of the component or product can be clearly listed.
If you are already familiar with the injection molding process, you know that the mold is under tremendous pressure so that the polymer will form. That’s why we can see the exact reasons for the detailed form in the components and products. Whether the need for simple, highly detailed, or complex output is on demand, you can be sure that it will and will be implemented.
Many types of polymers can be used.
Since the process does not rely on a single type of plastic, manufacturers or customers can choose other types of plastics for their intended products!
The product is very rugged and durable.
In order to make the product durable or to reduce the density of the polymer, the injection mold allows the use of a filter. This is necessary because everyone wants a reliable choice.
Mechanization reduces production costs.
With the advent of modern technology, manual labor has decreased, but the use of robots and machines has increased. Plastic molding is a highly automated process that reduces the need for manual labor or overhead costs. If these costs are reduced, the savings will be passed on to the customer.
As you can see, injection molding of Pet Preform offers many advantages. In addition to the ones mentioned above, this process is also considered to be environmentally friendly, because waste is produced very little, which is worth our thumbs up. Don’t you think?

Jilian Mold To Produce The Pet Preform You Want

According to Wikipedia, injection molding is a production method that produces articles by feeding raw materials into solid molds. The process can be accomplished with a range of components such as thermoset or thermoplastic polymers, elastomers, metals and glass. Selected components used to make the article will be fed into the machine, melted, mixed, and transferred to the mold cavity where it is then cooled and hardened. Jilian Plastics has a wealth of experience in Pet Preform injection molding, and can bring you the molds and products you want.
Type of injection molding
There are different types of manufacturing methods; liquid silicone rubber injection molding, reaction injection molding, plastic injection molding, thin wall injection molding, metal injection molding, and die casting.
Although each type is almost similar and equally beneficial, the plastic injection molding industry is very popular among manufacturers. But like any type of manufacturing method, it has its own set of advantages and disadvantages.
Advantages of plastic injection molding
Rapid production. This is a way to quickly manufacture a large number of products. In the normal process, one cycle can be completed in half a minute. Imagine how many plastic molds can be made in an hour!
Material and color flexibility. Due to the extreme flexibility of this approach, manufacturers and customers can choose a specific color or specific raw material to deliver the desired product. In the manufacturing process, various improvements can be made to the product before it reaches the final process.
An affordable method. Plastic injection molding machines can be run through programming equipment with little effort. This in turn does not incur additional costs for the entire production process. This is one of the reasons why plastic injection molding has become increasingly popular in plastic mold manufacturing companies for many years.
Disadvantages of plastic injection molding
High start-up fee. Depending on the customer’s needs and needs, the manufacturing process must first use a solid metal to make the mold prototype, which may seem very expensive at first. But considering its strength, the mold can be used multiple times, which may ultimately help customers save a lot of money. However, if the client’s funds are limited, low-cost molds can be used. Aluminum molds can maintain a relatively low initial cost.
Long preparation time. The time required to make the mold may take a while. Usually, it takes a month or more to make it. For customers who want things to get done as quickly as possible, this can be a dilemma.
Laborious modification. If the customer wants to make some modifications to the mold, this can be quite a challenge, because as mentioned earlier, it takes some time to make the mold. Making large products is easy, but if the customer wants to make the injection cavity smaller or more complex, the manufacturing company will work very hard and sometimes impossible.
As you can see, both positive and negative aspects are rare, but in general, the advantages outweigh the disadvantages. This is why many China Plastic Handle Manufacturers prefer this method over other types of injection molding.

Reasons For Affecting The Price Of Pet Preform

For plastic processing, there are many aspects that can affect the price of your Pet Preform. Helping customers optimize their designs and reduce manufacturing costs is our daily work. We have seen many CAD models with unnecessary features, but add a lot of processing time and processing costs, so we want to share our experience in how to make plastic prototypes better and cheaper in China.
CNC prototype manufacturing
1. As many design features as possible will preferably occur in one direction, preferably in the first operation.
2. Minimize the number of operations so that the material does not have to be flipped over and over to process features from all angles.
3. Avoid unnecessary features such as deep and narrow grooves, undercuts, small raised text and patterns, 0.5 mm or even thinner walls.
4. The 3D surface adds cost because the ball end mill must track the trajectory 100 times to achieve a reasonable finish.
5. For the radius feature of the outer radius, the standard nominal size is used, so special tools do not require grinding.
6. Design the part to flip at a 90 degree angle.
7. Make sure they can be machined in one plane.
If you are a designer and are working on your plastic prototyping project, consider all of these factors, which really affect manufacturing costs and processing time. If you have any difficulties in continuing your project, you are welcome to contact Jilian Plastics, a reliable China Plastic Handle Manufacturers to bring you advice and solutions.

China Plastic Handle Manufacturers Provide Production Efficiency

Don’t we all want to increase the productivity of Pet Preform in our factory? In order to lead the competition in the field of plastic injection molding, it is important to increase the productivity of the factory.
Typical objectives for injection molding are to optimize run size, reduce waste, reduce installation time, and preventive maintenance of injection molding machines.
If the run size is set correctly and your molding activity is excellent, then your mold handling team knows what to do. But even with proper training for the molder, the loading and unloading of the mold is very time consuming.
If your plastic injection molding process is not automated, it is a waste of time and money. This is also the part of most accidents that are waiting to be made during the injection molding process.
Buying another expensive injection molding machine does not shorten the installation time. Accelerating mold change time usually results in a quick recovery.
The rapid change of the mold system has brought you great success: QMC will not only shorten your production time, but plastic injection molding will also become a safer process.

China Plastic Handle Manufacturers To Meet Your Mold Needs

Injection molding of a Pet Preform involves injecting a molten polymer or resin into a cavity that is formed after cooling. When air is trapped in the cavity, voids, bubbles, and even burning marks may appear on the part. How to avoid these defects?
Venting is a big deal! Good venting helps produce high quality molded parts. Exhaust is a small gap that allows gas to pass through and plastic cannot pass. In addition, good injection parameters are better for reducing the occurrence of bubbles, so injection speed, injection size, temperature, cleaning, mold design, etc. are all factors we need to consider.
The melt flow of different plastics may be completely different. The plastic may cool too much, and when gas trapping is encountered, the filling pressure is not sufficient to keep the plastic following. That’s why sometimes we create overflows to improve short shots and ensure full fill.
Jilian Plastic Mould is a professional manufacturer of fast molds and rapid injection molding China Plastic Handle Manufacturers. We offer a range of services to meet the needs of low to large parts.
