Detailed Explanation of Five Parameters for Injection Molding

Injection molding is a kind of production behavior that plastic particles are molded into predetermined shapes by heating and melting. In this process, many factors of production have an important impact on the quality and production efficiency of the final plastic products.

Although different materials and different products have a variety of injection molding techniques, but we can summarize the process of injection molding parameters in the final product of the impact of various factors, so as to adjust the […]

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.

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 […]

Rapid Prototyping & Manufacturing China – Electroplating Process of Prototypes

Why shall the prototypes be electroplated?

After the prototypes or parts are formed, the metal luster on their surface is dull. While the surface of prototypes subjected to electroplating process are covered with metallic luster. Through electroplating, prototypes are rust and wear resistant, improved in electrical conductivity, lubricity, strength, heat resistance and weatherability. The surfaces of electroplating, prototypes are more attractive.

How to electroplate the prototypes?

Electroplating is a process to form a coating on the parts to be electroplated by connecting the metal at the anode […]

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 […]

Rapid Prototyping Service: Advantages and Disadvantages of PMMA Prototypes

The PMMA material is also known as plexiglass, which is one of the materials in fabricating prototype.

PMMA is a kind of plastic of high light transmittance which can be plasticized after being heated. It can allow about ninety-nine percent of light and seventy-three percent of ultraviolet (UV) to transmit through it. PMMA also has high mechanical strength that enables it to be used at high temperatures and adapt various climates. It is corrosion resistant and non-conductive. Under certain to conditions, its […]
