It is high polishing plastic lens mold for our USA customer . this part is used for some optical scanning device as 4 cavities high volume production project , now this production is running project in Asia Billion molding plant. there is also a new technology to cut the injection gate after the molding holding pressure. so we don't see where are the injection gate. This part need some A0 grade high polishing for the lens area with other location have light texture. The raw material is clear PC from makrolon. Asia Billion make more than 20 sets plastic lens mould for our customer and have good performance for all the production.

Plastic lens mould Workshop Overview:
Asia Billion lens mould Quality Control:
What is the in-mold hot-cut gating injection molding technology ?
Usually, after the plastic parts are injection molded, the material and the product are connected through the gate. The worker needs to trim the gate, which is labor intensive and the gate is not beautifully trimmed. The existing solution is to cut the gate from the top plate when the mold is opened. Both methods are cut after the mold is opened. Since the plastic has been cooled, the cut gate surface is not Aesthetics, product quality can not go up, still need multiple manual trimming to trim the gate, the labor intensity is still large, increasing labor costs.
In-mold hot cutting is the automatic injection molding process of the mold after the plastic mold is opened before the mold is cut or squeezed.
In short, in-mold hot cutting is the automatic separation technology between the material head and the product of plastic parts.
Advantages of in-mold hot cutting mould:
In-mold hot-cutting molds are widely used in various industrialized countries and regions in the world today. This is mainly because the in-mold hot-cutting mold has the following remarkable features:
1. In-mold gate separation automation, reducing dependence on people;
After the traditional plastic mold is opened, the product is connected with the gate. Two steps are required for manual shear separation. The in-mold hot-cutting mold advances the gate separation before the mold is opened, eliminating the subsequent process, which is conducive to production automation and reduces the number of people. rely.
2. Reduce the impact of product quality;
In the in-mold hot-cutting mold forming process, the automation of the gate separation ensures the uniformity of the gate separation, and the result is a consistent quality part, while the traditional manual separation gate process cannot guarantee the uniform appearance of the gate separation. Therefore, many high-quality products on the market are produced by in-mold hot-cutting dies.
3. Reduce molding cycle and improve production stability
The automation of in-mold hot-cutting avoids the useless artificial action in the production process, and the fully automated mechanical shearing of the product ensures the consistency of quality. In the large-scale production process of the product, it has an incomparable advantage over the traditional mold.
Disadvantages of mold hot cutting Mould:
Although in-mold hot-cutting dies have many significant advantages over conventional dies, mold users also need to understand the shortcomings of in-mold hot-cutting dies. To sum up, there are the following points.
1. Mold cost rises
In-mold hot-cutting components are more expensive, and the cost of in-mold hot-cutting molds is greatly increased. If the added value of the product is low, the output of the product is not high, which is economically uneconomical for the mold manufacturer. For many mold users in developing countries, the high cost of the in-mold scalding system is one of the main problems affecting the wide application of in-mold hot-cutting dies.
2. In-mold hot-cutting mold manufacturing process equipment requires high
In-mold hot-cutting dies require precision machining machinery to ensure. The integration and cooperation requirements of the in-mold hot cutting system and the mold are extremely strict, otherwise the mold will have many serious problems in the production process. For example, if the mold cylinder mounting hole plane is rough and the sealing member cannot seal the oil, the cylinder can not move. The cooperation between the cutter and the mold core is not good, and the cutter can not be produced and cannot be produced.
3. Operation and maintenance is complicated
Compared with the in-mold hot-cutting mold, the in-mold hot-cutting mold is complicated to operate and repair. If improper use is used, it will easily damage the hot-cut parts in the mold, making production impossible, resulting in huge economic losses. For new users of in-mold hot-cutting dies, it takes a long time to accumulate experience.
