What problems can occur in the injection molding process of spray-free plastics?

Green water and green mountains, is the silver mountain of gold, environmental protection issues are becoming increasingly prominent, environmental protection industry, environmental protection products have become an important direction of China's economic development. Many polluting enterprises have been ordered to rectify, and the paint industry has been the first to bear the brunt. As an environmentally friendly material that can replace traditional materials, spray-free plastic is now a popular material due to the favorable policy and market. Restricted by the structure of the product, spray-free materials also have obvious shortcomings, next, I have compiled for you the problems and solutions in the production and injection molding process of spray-free plastic.

I. Spray-free plastic

Spray-free materials, refers to the direct addition of colored pigments (metal powder, pearlescent powder, etc.) in plastic, and then through direct injection molding into, extrusion processing into different plastic products, without the need to spray.

Two, no spraying plastic advantages

1. environmental protection

2. No color loss

3. Cost reduction

4. recyclable

What are the problems of spray-free plastic in the process of injection molding?

Spray-free plastic

3. Problems and solutions in the production and injection molding process of spray-free plastic

Spray-free plastic in the production and injection molding, there will be flow marks, fusion marks and other problems, coloring process is not handled well, may lead to uneven coloring results. So how to deal with these difficulties?

1. Switch to base material with good flowability

2. choose spherical pearlescent powder or aluminum silver powder

3. adjust the structure of the product to make the defects hidden or reduced

4. use auxiliary equipment, such as: mold temperature machine, rapid cooling and heating equipment to improve this problem.
