Bicolor Injection Mold Maintenance

Check loose air holes for rust or moisture

 
If you find rust or moisture near a hot runner vent, it means internal condensation or a possible water pipe rupture. Moisture can cause a fatal short circuit to the heater. If the machine is shut down at night or on weekends instead of running all year round, the chance of such condensation on an injection mold increases.
 
You should have measured the resistance of the heater when you first started using it, […]

Insert Molding VS Coating Molding

Injection molding of inserts is similar to other molding methods, but there are some differences in each process. Injection molding involves injecting one or more molten plastics into a mold to form a single finished product.
 
Coating molding
What is the coating molding? Simply put, the coating process can be plastic, flexible or flexible.
There are physical and chemical methods to realize the coating moulding (including overmolding). The former, for example, relies on snap design, surface tapping threads, and then coated with […]

Sensor injection parts – copper nut and ABS processing

Injection molding process is not static, logical, because of the different products, different materials, different injection molding machine and material preparation and so on the different conditions, injection molding process will produce many uncertain factors, so as the injection molding processing workers, according to specific conditions to the corresponding process optimization adjustment is the highest embodiment of injection molding processing technology. Therefore, the optimization of the processing of copper nut +ABS for injection molded sensor accessories can be carried […]

Draft Angle of Injection Mold

What is the draft angle?
The draft angle is the angle between the side tangential direction of the intersection of the workpiece and the parting surface of the die and the normal direction of the parting surface of the mold.
 
Why is the draft slope used in injection molds?
Reduce the chance of parts damaged by friction during release
 
Reduce the chance of wear and damage to injection molds
 
If necessary, ensure uniform, smooth, scratch-free surface treatment
 
Ensure other surface finish and texture integrity and uniformity
 
educe overall cooling […]

Injection Molding Processing Technology of Two-color Mould

In recent years, with the development and universality of plastic industry. Plastic products are used more and more widely, such as household appliances, instruments, building equipment, automotive industry, daily hardware and many other fields. The proportion of plastic products is increasing rapidly. However, with the increasing trend of plasticization of industrial products and daily products, the strength and accuracy of plastic products are also constantly improving. Therefore, in order to make the mould have better strength and accuracy, it […]

Notes for PA Injection Molding

Characteristics of PA: Nylon has the characteristics of toughness, wear resistance, self-lubrication, smoothness, non-toxicity, anti-bacterial and strong water absorption. In addition, its tensile strength and stiffness will decrease sharply with moisture absorption. Then, the size of the finished product varies greatly.
 
Advantages of PA:
 
It has high mechanical strength, good toughness, high pressure resistance and elongation strength, twice as much as ABS injection parts.
 
Nylon injection parts have excellent fatigue resistance, smooth surface, small friction coefficient and good wear resistance. It also […]

NC Processing Flow of Injection Mold

CNC center has been widely used in the current market. Compared with other machine tools, the mechanical part of CNC center is not different from other lathes, only in the form of control. So how does the CNC machining center work?
 
CNC machining center is also called CNC machine tool. Generally speaking, the sequence of CNC processing technology should satisfy the following rules:
 

Milling before drilling

 

Processing the inner cavity first, then the contour.

 

According to the sequence of working procedures, tool diameter […]

What performance is required when using injection mold steel materials?

In the process of injection mold processing, the selection of raw materials will play an important role in the overall life of the injection mold and the quality of the plastic products produced. What performance requirements should be achieved when selecting the steel materials for injection molds?

Good surface hardness and wear resistance

The hardness of the injection mold is usually below 50-60HRC. The surface hardness of the heat-treated mold is high. The mold is subjected to large compressive stress […]

Why do we choose injection moulds to produce products?

The sustained development of the plastic industry has also promoted the development of the injection mould industry, so why is the injection mould so popular? The following six points are enough for you to have a basic understanding of injection moulds.
 
1) High accuracy
 
As a highly precise processing method, plastic injection moulding process can be used to produce almost any kind of diversified plastic parts. Although there are some design limitations, the manufacturing of injection moulds ensures the high precision […]
