Heat treatment and production process of precision injection molding

In the process of heat treatment, the deformation of precision injection mold often occurs. In order to prevent this kind of bad phenomenon, as long as we grasp the deformation law and analyze the causes, different methods can be used to prevent the deformation of mold, which can be reduced and controlled. In general, the following methods can be adopted to prevent the deformation of precision injection mold during heat treatment.
(1) Reasonable material selection: for precision injection mold, micro […]

Analysis of injection process of PC plastics

PC plastics have excellent properties, high transparency, good impact toughness, creep resistance, wide temperature range. PC plastics have the following process characteristics
The sensitivity of melt viscosity to shear rate is small, but to temperature is large, there is no obvious melting point, the viscosity of melt is high, the resin is easy to hydrolyze at high temperature, and the product is easy to crack. In view of these characteristics, special attention should be paid to differential treatment: to increase […]

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. […]

How to deal with the weld lines of injection parts?

What is weld lines
Weld lines are the most common defects in injection molded products. Except for a few injection molded parts with very simple geometry, weld lines occur in most injection molded parts (usually with one line or V-shaped groove), especially in large-scale complex products requiring multi gate mold and inserts.
Weld lines not only affect the appearance quality of plastic parts, but also the mechanical properties of plastic parts, such as impact strength, tensile strength, elongation at break, etc. […]

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 […]

To standardize the management of mold factory

(1) Standardized management of product and drawing data
Effective management can ensure the comprehensiveness and consistency of data, and make the data share and query effectively. To prevent problems caused by data inconsistency and drawing non-standard from being found and corrected in time, resulting in rework and maintenance of the mold, increasing the manufacturing cost of the mold, and affecting the delivery time
(2) Establish the company’s own quality inspection mold department, standardize various inspection methods. Get rid of fluke. Strengthen […]
