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 […]

The Significance of Numbers at the Bottom of Plastic Bottles

The bottom number of plastic bottles represents PET (polyethylene terephthalate). At present, mineral water, carbonated beverage and functional beverage bottles are made of this material. It is heat-resistant to 70 C and easy to deform. It may release carcinogens after 10 months of use. In hot weather, do not put mineral water in the open air or in cars, nor directly flush boiling water into mineral water bottles.

2 stands for HDPE (High Density Polyethylene): It is mainly used to […]

Requirements and precautions of Injection mold

Due to the high precision of manufacturing and processing precision of injection molds, the production and processing technology is also complicated. Therefore, the processing and production costs of plastic injection molds are generally high.
The selection of materials for injection mold manufacturing must meet the following requirements:
1. The injection mold steel should have good processing performance. When working in high temperature environment and heat treatment, the deformation should be small.
2. The working surface of the melt channel in the cavity […]

What kinds of engineering plastics are used in automobile plastic parts?

Nylon Material (PA)

Nylon is mainly used in automotive engines and engine peripheral components, the main varieties are GFPA6, GFPA66, enhanced flame retardant PA6 and other products.

Application in automobile engine peripheral parts: Because the engine peripheral parts are mainly heating and vibration parts, most of the materials used in the components are glass fiber reinforced nylon. This is because nylon has good comprehensive properties. The main properties of nylon modified with glass fiber have been greatly improved, such as strength, […]

Basic Requirements for Injection Molding Operators

First inspection and self inspection in injection molding production

1) Before production, the operator must submit the first mold product to the inspector for self-inspection and then to the inspector for first inspection. Only after the inspector notifies that it is qualified, can the mass production be carried out. The first mold sample should be left on the injection molding machine for self-inspection in production.

2) If the products in production do not meet the quality requirements, the monitor should be […]

Detailed Explanation of Injection Molding Process for PP Plastics

“Plastic properties are the basis of injection molding technology”. Mastering the technological properties and characteristics of various plastics is a basic professional knowledge that every injection molding worker must know. The performance of plastics is the basis for setting “injection molding process conditions”. It is also the reason that must be considered when analyzing the quality problems and abnormal phenomena in the process of injection molding. One of the elements.

PP, commonly known as polypropylene, is also known as “100 […]
