Common Used Material Property of Injection Molded Part

PC: PC is the abbreviation of polycarbonate, with excellent electrical insulation, elongation, dimensional stability and chemical corrosion resistance, high strength, heat resistance and cold resistance, but also has self-extinguishing, flame retardant, non-toxic, coloring and other advantages.

Applications: Broad-wave transparent optical instruments; flame-retardant and environmentally friendly telecommunications appliances; surface metallized automotive parts; food containers with low residual harmful substances; anti-cracking and embrittlement medical devices
 
ABS: (ABS resin) (acrylonitrile-styrene-butadiene copolymer), good rigidity, high impact strength, heat resistance, low temperature resistance, chemical resistance, mechanical […]

How to Control The Chromatic Aberration of Injection Molded Products

Chromatic aberration is a common defect in injection molding. It is not uncommon that the color difference of the matching parts causes the rejection of the injection molding machine in batches. There are many factors affecting chromatic aberration, including resin, masterbatch, masterbatch mixing with raw materials, injection molding process, injection molding machine, mold and so on. Because of the wide range involved, chromatic aberration control technology is also recognized as one of the more difficult technologies to master in […]

How to Distinguish Mold Grades? Take A Look at The Five Major American Mold Standards

The price of the export mold will be more expensive, but it is expensive because the standard is different. The American Plastics Industry Association (SPIAN-102-78) divides the molds into five categories. Each of these five types of molds has its own requirements, and this classification of molds can only be applied to molds with 400 tons or less of injection molding machines.

101 type
 
The cycle can be up to 1 million times for high production. The best mold material is […]

What Are The Main Reasons Affect Mold Failure?

Failure often occurs in the use of molds, from the actual point of view, we focus on several failure modes. There are five main types:
 

Failure of plastic deformation

The main reason is that the strength level of the mold material is not high; or the heat treatment process is not correct, not to achieve the best strength and toughness of steel; improper use of the die causes local overload; for hot-working mold softening at high temperature will also lead to mold thermoplastic deformation […]

Injection Molding Design – Summary of Requirements on Mold Design Process

The mold design is different from product design, because it is a process design itself. The basic requirements for mold design are: 

The mold shall be able to complete the process of parts processing.

 

The equipment on which the mold is used shall be specified; and the technical parameters of the equipment shall be complied with.

 
 

The parts molded during the validity period of the mold shall have the dimension tolerance within the allowed range of parts drawings.

 

For prototype mold, the mold […]

Sharing Specific Mold Processing Methods

(1) Determine the type of mold.
Such as pressing die (open, semi closed, closed), casting die, injection mold, etc.
mold making
(2) Determine the main structure of mold type.
The ideal die structure is to determine the necessary molding equipment, the ideal cavity number, under absolutely reliable conditions can make the mold itself work to meet the technical and economic requirements of the plastic parts. The technical requirements for plastic parts are to ensure the geometry, surface finish and dimensional accuracy of plastic […]

What Are The Characteristics of Injection Molds?

In the market, most of the molds we come into contact with are injection molds, which inject plastic materials into the molds to form the products needed for sale. In the mold industry, injection moulds are widely used. What are the characteristics of injection moulds? Injection mold is a kind of processing method used in batch production. It is mainly used in industrial field. The process of injection mold is to inject the melted material into the mold cavity […]

What Needs to be Determined before Plastic Mold Design?

Before designing the plastic mold, we must find out the required plastic parts and production conditions. For this reason, we need to do the following work.
 
(1) Acceptance of mission documents
 
The task document for molded plastic parts is usually presented by the designer of the product.
 

the formal drawing of the specimen is signed, and the grade and transparency of the plastic are specified.
Specifications or technical requirements for plastic parts.

3.Production output.

samples of plastic products.

 
Usually the mold design task statement is put […]

Application of Two Color Mold in Automotive Mold Industry

In our demand for molds, there is a kind of called two-color mold, generally like a car lampshade, you can see, there are white and red connected, that belongs to the two-color mold. Some people will be curious, how can mold products come out on both sides of the red intermediate white? Two-color mold is generally used by injection molding, but two-color mold we need to inject two colors of materials. Today, we will introduce the use of two […]
