How to solve the lack of glue in injection molding products?

Many injection molding plants have encountered the problem of lack of glue in plastic open mold injection molding products. The elegant name is insufficient filling.
It means that the material cannot completely fill the formed product. The direct result is that we can’t get the shape products we need. Generally speaking, this is due to the insufficient fluidity of raw materials and the insufficient calculation of the amount of glue filled in the product.
But we encountered a very troublesome situation […]

Foresight of mold design in Dongguan injection mold factory

As a mold designer of Dongguan injection mold factory, we must have foresight in design: list all possible mold problems, and then make foresight mold products with reference to past design ideas.
The mold designers of Dongguan injection mold factory fully consider the product structure and assembly. At the same time, they also need to consider the product demoulding, waterway layout, gate distribution, etc. the following will briefly introduce the design points of the product’s ribs, buckles, nut holes and […]

What should we pay attention to when TPE plastic injection molding?

What should we pay attention to when TPE plastic injection molding?
1. TPE plastic injection molding in the process of injection molding, the process and appearance of raw materials need to be checked before TPE molding. Dry the raw materials and determine the water content. Under the condition of high temperature, the moisture content of TPE raw materials is required to be less than 5%, or even 2% ~ 3%. Therefore, vacuum drying oven is commonly used to dry at […]

How do general injection molding factories solve the problem of product pitting?

Many technicians of injection molding products factories will find that sometimes there are many pits on the surface of injection molded products when plastic products are processed and injected.

It has a great impact on the appearance. The inspectors of the injection molding product factory should know that it is difficult for customers to accept such products with appearance problems.
We consulted technician and […]

What if bubbles appear in the production of silicone mold?

Causes of bubbles:
The reason for bubbles in the manufacturing process of silicone mold is that air will be mixed in the mixing process of silicone and curing agent, and bubbles will appear. If there is no vacuum in the process of making the mold, the silicone mold will produce bubbles.

How much do you know about the solution of snake flow mark in injection molding process?

In the process of injection molding, it is easy to have snake flow marks and other adverse problems. Serpentine flow mark refers to the irregular flow line with gate as the middle on PC products. Different from the “fingerprint” line, the turbulent flow mark appears along the material flow direction rather than perpendicular to the material flow direction.
The reason for its formation may be that the melt injected into the mold cavity is greatly impacted, resulting in negative and […]
