Injection mold factory’s know-how to do well in products — paying attention to injection molding process

Some products of the injection mold factory are molded with PC (polycarbonate) or PC + ABS materials. Due to the poor fluidity of PC, the process is usually filled with high mold temperature and high material temperature: the gate used is usually point gate, and graded injection molding is required to find the gate position and injection pressure maintaining switching position, It will be very helpful to solve the gate gas mark and flash anomaly.
 
Therefore, if our injection mold […]

Injection molding products appear crazing how to do, mold design to solve your worries!

The crazing defect of plastic mold injection molding plant in the process of injection molding products can not be solved after debugging by various methods. At this time, it is necessary to consider whether the solution to such problems is not considered at the beginning of mold design. Next, the machco mold designer will analyze why the mold design can solve the product crazing problem.
 
Through the inspection of the following four aspects, the problems of this kind of plastic […]

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. Different from the impurity problem of black spots, pitting mainly produces many pits on the product surface.
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 are the temperature control of plastic mold

The temperature of plastic mold has a great impact on product molding quality, which is one of the three process conditions of injection molding. For precision injection molding, there is not only the problem of temperature, but also the problem of temperature control accuracy. Obviously, in the process of precision injection molding, if the temperature control is not accurate, the fluidity of plastic melt and the molding performance and shrinkage of products will not be stable, so the accuracy […]

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 […]
