Brief Introduction of Injection Molding Process

The injection molding process includes preparation before molding, injection process and post-processing of plastic parts.
 
Preparations before molding include the inspection of raw material appearance and the determination of technological properties, preheating and drying, cleaning of injection machine barrel, preheating of inserts and selection of release agent when demoulding is difficult. Sometimes it is necessary to preheat the mold.
 
During molding, powdered or granular materials are fed from the hopper into the high-temperature barrel for melting and plasticizing to become viscous […]

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 […]

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

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. […]

China Rapid Prototyping: Spray Painting Treating Process of Prototypes

If it needs any spray painting treating process after finish the prototypes, please note that the SLA rapid prototyping work-piece doesn’t suit the high glossy surface treatment, because it has used the photosensitive resin, which is not good for adhering oil paint to achieve the desired glossiness effect. The CNC Prototype Machining work-pieces, including made from PP and POM, doesn’t suit to deal with the surface for spray painting, because the materials have no adhesiveness with spray painting. Before painting, it needs to polish […]
