How to solve the matte surface of plastic injection parts?

Low gloss means that the surface is dark and dull, and the transparency of transparent products is low. There are many reasons for poor gloss. The surface gloss defects of general products can be divided into the following three types: plastic mold failure, improper molding conditions, improper use of raw materials.
 
Injection mold failure
Because the surface of the plastic part is the reproduction of the surface of the mold cavity of the plastic mold, if the surface of the plastic […]

Raw material purchasing process of plastic mould

In order to maintain stable quality and high production life of plastic mold, the importance of the quality of steel used is self-evident. The quality of steel directly affects the life of plastic mold quality. Therefore, in the selection of plastic mold steel, we need to consider the mold steel material suitable for customer demand.
In general, if the customer requires a high output, the steel with higher hardness must be selected, otherwise it is easy to wear and tear, […]

What causes short shot of plastic mold in injection molding?

Short shot refers to the phenomenon that the cavity of plastic mold is not completely filled due to the insufficient fluidity of plastic, resulting in incomplete plastic products. The main reason is improper injection pressure and speed (including excessive pressure loss caused by resistance), which is mainly affected by the following aspects:
 
1、 Injection molding machine
(1) Insufficient injection molding capacity – this is caused by the high capacity of the injection molding machine, which may also be caused by insufficient […]

Customized processing of plastic injection mold for JasonMould automobile

The automobile industry has developed rapidly in the past ten years, and more and more new products have entered the market, such as new energy vehicles. A large number of automatic parts are made of plastic. As a new material of automobile parts, plastic parts can reduce the weight of automobile and save energy, so they are widely used in automobile industry. This means that a large number of plastic injection molds are needed to produce the required plastic […]

Why is the delivery time of injection mold difficult to control?

There are many factors that are difficult to control in the whole production and manufacturing process of injection mold, among which the delivery problem of injection mold is the more difficult point to control, so what causes the difficult control of the delivery of injection mold?
Mingyang Yutong focuses on precision mold manufacturing for more than ten years
1. Firstly, the customer’s order information has not been finalized, and the contract and design changes frequently.
2. Injection mold is a customized product, […]

Application of injection molding in plastic gear

With the development of plastic industry, plastic products are more and more widely used in all walks of life with its unique advantages. At the same time, the important position and role of plastic mold injection molding in production and manufacturing are gradually recognized by more and more people.
Gear, a special mechanical part, is gradually replaced by plastic. Compared with traditional metal gear, plastic gear has the following advantages:
① Plastic gear is lighter than metal gear, which can reduce […]

The advantages of spray painting on the surface of plastic parts

The surface of the plastic part can be sprayed to ensure the brightness of the product. Because plastic is so hard to embody, plastic parts look darker, and even darker if they are covered in leather. Therefore, in the pursuit of a beautiful surface, Some customers requires to spray a layer of  painting on the surface of plastic parts. This will ensure the brightness of the product.
Spraying the surface of plastic parts can reduce the scrap rate of parts. […]

Factors affecting the number of cavities in Plastic Injection Molds

The cavities in Plastic injection mold is not the more the better, also not all molds can be done with 4 cavities or 8 cavities. So what are the factors affecting the numbers? Let’s have a look below:

Relationship between the product size and equipment.

When the part belongs to large or medium size, generally speaking, single cavity is used. On the one hand, it is necessary to consider the fluidity of plastic material filling mold when injection molding, so as […]

How to prevent stripe defects in precision injection molding?

As we all know, the stripe defect in mold is a very serious matter, it will directly affect the accuracy of injection molding, and will also lead to product scrap, so we must pay attention to. So, how can we avoid this defect?
Proper design, careful processing, reasonable mold repair and timely nitriding are the key measures to prevent the occurrence of stripe defects in precision injection molding.
It should be processed in strict accordance with the requirements of the drawing, […]

What will be caused when injection mold testing in many times?

The design of the injection mold was not fully collectively reviewed, and the structure of the injection mold was unreasonable, which caused the injection mold to undergo multiple improvements after the test, which made the injection mold cost exceed the budget.
If it can be solved after several improvements, it is relatively fortunate. There are many cases that are unsatisfactory, and even the injection molds have to be scrapped and reworked. This cost cannot be controlled.
There are also cases where […]
