What should we do to control the quality of plastic mould?

Now the plastic mold industry has higher and higher requirements for machine equipment and testing instruments! The price of CMM and other testing equipment is also increasing, which shows that the improvement of quality is the future development direction of the whole plastic mold industry. After more than 10 years of continuous exploration and learning, Shenzhen Mingyang Yutong technology has summed up that to ensure the quality of plastic mold products, it is also necessary to strictly control each […]

Design Of Ultrasonic Line

Ultrasonic welding in the assembly of plastic parts is commonly used to a process. ABS, PC+ABS, PP, PC, etc. these materials are suitable for ultrasonic welding. Generally used for ultrasonic two parts are required to be the same material. Ultrasonic bonding will be better. If nylon or POM is used to ultrasonic with ABS, this is not feasible.
 
Ultrasonic welding has a lot of advantages, the most critical is to meet the waterproof requirements of the product, the second ultrasonic […]

Black spots of common problems in injection molding

What is a black spot? Black spot refers to the black spots or stripes on the molded products.
Causes of black spots on injection molded parts:
1. Resin decomposition
As plastic is a chemical, it will decompose gradually when it is heated above the melting point. The higher the temperature, the longer the time and the faster the decomposition. In addition, there are some areas in the barrel that are easy to retain resin, such as check check valve and thread. The […]

SPI Mold Standard–Wall Thickness Design

Product structure is undoubtedly the key factor to determine the price of the mold, the realization of a product function has a variety of different design, different design determines the mold manufacturing method is not the same, determine the price of the mold will be different, some structure only need us to pay attention to some design principles, may be able to save a lot of cost.
 
If we ignore the wall thickness of the product, the appearance problems will […]

Characteristics and injection process of PC + ABS injection material

What is PC + ABS material?
PC plastic is a new type of thermoplastic with 90% transparency, so it is called transparent metal. It is very hard, with high impact strength and high dimensional stability, as well as a wide range of application temperature, good electrical insulation, heat resistance and non-toxic properties ABS is a tough and rigid thermoplastic. It is a blend or terpolymer of acrylonitrile, butadiene and styrene. Styrene endows ABS with excellent moldability, gloss and rigidity; acrylonitrile […]

Key Points Of Boss Design

Screw post is also called boss, which is a feature of most products. What key points should we pay attention to when designing the structure? Let’s have a look:
 

The wall thickness of the boss, at the time of structure design, we need to consider the strength of the boss, so as far as possible the post do thick wall thickness, but this will lead to positive forming parts shrink, we can design according to the main body of the […]

How to choose injection mold steel?

How to choose the injection mold steel reasonably is a complex project, and it is also the key link of the injection mold manufacturing. This is an important work related to the service life of the mold and the cost of the injection mold. Generally, the materials used to make plastic injection mold need to have certain hardness and wear resistance first. Secondly, it should have strength and toughness. Before choosing the injection mold steel, we need to know […]

The reason bubble caused in plastic product of injection molding

How should plastic product appear bubble to do? Our engineer’s answer is that the reason may in the equipment, plastic mold, and may also in the injection process, the following is the reason analysis of the process, hope to help you solve the problem.
 

The back pressure of screw pre-molding is too low and the rotation speed is too high, which causes the screw to return too fast, and the air is easily pushed to the front end of the […]

5 benefits of custom injection molding

If you need to mass produce the same plastic product, injection molding is your first choice. This low-cost process can produce high-quality parts in large quantities.
But do you know the material and process of injection molding? JasonMould takes you to the next 5 options for custom injection molding benefits.
1. Product customization: change to the color or type of material you want to use. Other additives can also be added to enhance the finished part and even other characteristics, such […]

How to tell the difference between PP and POM material?

In recent years, more and more kinds of plastic products come into our life, at the same time the development of injection molding technology get injection molding products replace other material life and industrial supplies, now almost all things are linked with injection molding parts. So how to distinguish injection plastic material is also a need to pay attention to in daily life. Here Jasonmould briefly introduces you to the difference between PP and POM materials.
 
The method is as […]
