SJ Group SCIENTIFIC MOLDING Introduction

Why we make injection molding as per scientific molding? What is the benefit?

Ways of getting tooling quote right

How to provide a accurate mold quote for customers

Why Switching From Metal to Plastic Parts

The value and meaning of switching-from-metal-to-plastic-parts

Injection molding surface quality and inspection requirements

The raw materials must be fully dried according to the process requirements, without moisture, otherwise there will be silver streaks on the surface after injection

Parameters of Plastic Injection Molding

The injection pressure is provided by the hydraulic system of the injection system. The pressure of the hydraulic cylinder is transmitted to the plastic melt through the screw of the injection molding

Engineering technology of Plastic Injection Molding

In the injection molding process, the complete technology is an indispensable engineering technology.

How much does mold temperature affect injection molding?

Mold temperature is the most important variable in injection molding-no matter what kind of plastic is injected, it is necessary to ensure that the mold surface is basically wet.

The development trend of mold and plastic products industry

With the gradual transformation and upgrading of the industrial structure, the gradual increase in the proportion of high-end products

What factors in injection molding processing are related to production costs

The relationship between injection cycle time and production cost. Under the premise of ensuring product quality, the shorter the injection cycle time, the better

Talking about the phenomenon that the injection mold cannot be opened

First: Improper adjustment of the mechanical origin of the mold clamping when the injection molding machine leaves the factory.

What is the impact of injection molding process conditions on products

The first to bear the brunt is plastic materials. The complexity of the properties of plastic materials often determines the complexity of the injection molding process.
