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 […]

5 Trends of Domestic Plastic Mold Development in The Future

Plastic industry has a history of 120 years. After more than a century of great development, plastic is now integrated into all aspects of human life and work, from machinery, electronics, automobiles, information, aviation, aerospace, light industry, military industry, transportation, building materials, medical, biological, energy and other industries. And 60% – 80% of the above industry parts need to rely on mold processing molding, so mold as an important material molding process equipment in the history of the development […]

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 […]

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 […]

Development trend of Rapid Tooling Technology

With the development of rapid prototyping and rapid tooling manufacturing technology, in the near future, high precision rapid tooling will have great development. It is mainly manifested in the following aspects:
 
First, improve the performance of rapid tooling and improve the accuracy of rapid tooling. Good mold performance and high die accuracy are the key issues in the application and promotion of rapid tooling.
 

Improving the performance of the rapid tooling: In order to obtain high-quality product parts and better mold […]

What Are Suitable Materials for Prototype?

In the following four materials for prototype, only black PC can be spliced, while the other three materials cannot be spliced but manufactured in one piece instead.
1.Prototypes of conventional products are generally made of ABS material,and the prototypes made of ABS are easy to machine,and more pleasant looking after treatment.
2.Prototypes of high temperature resistant products can be made with materials including(1) epoxy resin; (2)bakelite; (3) black PC; (4) PA (nylon).
3.Prototypes of wear resistant products can be produced withPOM or PA. […]

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 […]
