Is the injection product cracked again? This article teaches you to deal with cracking easily

In our injection molding, due to various factors, we often see some uncomfortable cracking after molding, which often makes us feel headache. So today, let’s talk about how to deal with the cracking of plastic parts.
Cracking includes filamentous cracks, microcracks, white top, surface cracking of parts, or trauma crisis caused by sticking parts and flow channels. According to the different cracking time, cracking can be divided into demoulding cracking and application cracking. There are three main reasons
Processing reason:
(1) If […]

Delamination and peeling of injection molding

The causes of delamination and peeling in injection molding products are as follows
Material temperature is too low, injection mold temperature is too low, screw speed is too fast, resulting in internal stress.
The cold material hole is small, the fluidity is poor, and the material is cooled too fast.
The holding pressure is low and the back pressure is too low.
The raw material is mixed with impurities.
Release method:
Increase the material temperature, die temperature, reduce the shear force of melt flow, reduce […]

Selection of gate position in precision injection mold design

The gate design of precision injection mold can make the flow velocity of molten plastic transported by sub channel produce acceleration, form ideal flow pattern and sequence, and quickly fill the mold cavity. At the same time, it also plays the role of closing the mold cavity to prevent the molten material backflow, and it is convenient to separate the gate from the plastic part after molding. Since the gate plays such an important role in the design of […]

How to prevent the repeated test of injection mold?

Most people are particularly concerned about “how much is the cost of the injection mold?” In general, the cost accounting of injection mold is mostly traceable. But there are also some cases where the cost of the injection mold will be increased. One of them is repeated trial. The repeated trial mold not only increases the cost of injection mold, but also delays the time of product putting into the market, which is very disadvantageous for customers to seize […]

What causes short shot of plastic mold in injection molding?

Short shot refers to the phenomenon that the cavity of plastic mold is not completely filled due to the insufficient fluidity of plastic, resulting in incomplete plastic products. The main reason is improper injection pressure and speed (including excessive pressure loss caused by resistance), which is mainly affected by the following aspects:

1、 Injection molding machine
(1) Insufficient injection molding capacity – this is caused by the high capacity of the injection molding machine, which may also be caused by insufficient […]

How to ensure the precision of injection parts in high precision injection mold factory?

The characteristics of high precision injection molding are as follows:
The specification of injection molded parts has high precision and small dimensional tolerance.
To ensure the requirements of high precision injection molding, the necessary standards are as follows:
1. Good die material, enough stiffness, die specification accuracy, smoothness and precision positioning between the templates should be high.
2. High precision injection molding machine should be selected.
3. High precision injection molding process should be selected.
4. Plastic materials suitable for high precision injection molding process […]
