Plastic Injection Molding

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 […]

How to prevent shrinkage fluctuation of precision injection molding products?

Precision injection molding must be based on the premise that the mold can be made according to the required size. However, even if the mold size is fixed, the actual size of the product varies with the actual shrinkage. Therefore, the control of shrinkage rate is very important in precision injection molding.
Whether the mold design is appropriate or not determines the shrinkage rate, which also varies with different resin batches. If the pigment is changed, the shrinkage rate will […]

Suggestions on the installation of injection mold

1. Preparation before installation
Confirm the cooling water channel, and the screw depth into the machine plate is 1.5-1.8 times of the screw diameter. If the screw is not enough, it is easy to slide the teeth, and there is a risk of mold falling. Confirm whether the operators, materials, tools, documents, equipment and auxiliary equipment required for production are complete.
2. Method of lifting formwork
When the hanging die is not horizontal, there will be segment difference between the front and […]

Advantage manufacturer of transparent plastic injection molding — JasonMould

Transparent plastic products have strict requirements on the appearance of the products, which need to maintain the penetration rate of the products. Therefore, the surface of the products should not have any defects such as stripes, pores, whitening, haze, black spots, discoloration and poor gloss. So in the whole process of injection molding, there are very strict requirements for raw materials, molding equipment and injection mold.
In order to produce the best transparent parts, JasonMould not only achieves fine production […]

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 […]

Shenzhen small batch injection molding manufacturers choose JasonMould

With the continuous shortening of product renewal cycle, small batch production of plastic parts is increasing. In addition, small batch production of plastic parts is also needed in product testing. In order to meet the needs of small batch production, a variety of injection mold suitable for small batch production came into being.
 
As a 15 year injection mold manufacturer, JasonMould established injection molding department in early 2010 to meet market demand, and purchased new Haitian injection molding machines with […]

Shenzhen two color mold factory which good?

Two color mold is an injection mold in which two kinds of plastic materials are injected in the same injection molding machine, and the products are molded only once. Generally, this injection molding process is also called two-color injection molding. At present, there are many mold factories can produce two-color mold, but the quality is also uneven. There are many plastic mold factories in Shenzhen alone. So in many mold factories, which two-color mold factory is better?
JasonMould Industrial Co., […]

What should we pay attention to when we try new mould in Shenzhen?

When we receive a new die which needs to be proofed and tested, we are always eager to try out a result earlier and pray that the process will be smooth so as not to waste working hours and cause trouble
1) Check the mold as soon as the machine is opened to confirm whether all the mechanisms of the mold are smooth. If there is a problem, Shenzhen mold enterprise reminds you to stop the action immediately, so as […]

Analysis of possible factors of discoloration of black spots on injection molded parts

1. Machine
As the heating control system is out of control, the barrel is overheated and decomposed into black
Due to the defects of screw or barrel, the molten materials are stuck in and accumulated, and the decomposition is caused by long-time fixed heating. Check whether the rubber head kit is worn or whether there are metal foreign matters in it
Some plastics, such as ABS, are cross-linked and coked by high heat in the barrel. They are difficult to melt under […]
