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. 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 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 can we solve it?
Methods a vacuum machine is used in the process of making silicone mold, which can eliminate the generation of bubbles. Put the stirred silicone into the vacuum […]

Why do you visit the factory when consulting the injection molding manufacturer?

When consulting the quotation of injection molding manufacturers, why do injection molding manufacturers try to invite customers to the factory for on-site investigation and then quote? Most customers don’t quite understand it. If they think your quotation is reasonable, it’s not too late for me to go to the factory again. In fact, it’s not because you don’t know whether you contact a manufacturer that can really solve your needs.

If not, your cost will increase; Once there is a […]

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 […]

Is the failure of tension structure of large injection mold a problem of mold design?

The failure of the tensioning structure of large injection mold is a very dangerous processing thing. When testing the mold, it is necessary to detect the possibility of such problems to avoid such problems during processing.
So, is this problem caused by mold design? The answer is yes!
In the design of injection mold, fixed distance tensioning mechanisms such as swing hook and buckle are generally used in fixed mold core pulling or some secondary demoulding molds. Because these mechanisms are […]

What factors affect the price of injection mold?

In the injection mold industry, there is no standard way to calculate the mold price, because now in the injection mold industry, the competitiveness is too great, because some mold suppliers quote the cost price to customers just to make money in subsequent injection molding processing. In fact, without knowing the material, size, acupoints, accuracy, appearance requirements and other parameters of the mold, the price of the injection mold quoted is inaccurate. It’s hard to say, it’s an irresponsible […]

Dj Mold tell you: if the materials are selected well, the product design is half successful!

Many designers say in product design, the sad one is the selection of materials. For us, so are customers! If the customer chooses a material as the material for the production of the product, but if it is not verified by appropriate experiments, once there is a problem, it is a big problem!
In the aspect of material selection, no matter the design of injection molding products manufacturer and how careful the customer is, it is not too much.
So how […]
