Unscrew injection molding, as its name implied, there is thread in the plastic part for easy assemble and connection with other screw parts. Unscrew molding products are common in our daily life as we can see the caps form our bottle. This is kind of a very basic and normal unscrew molding products. 

Unscrew molding is a very important form of injection molding. Unscrew mold manufacturing technology is becoming more and more mature. However, many mold factories cannot ...

As a good reputation manufacturer in China, we here share the basic injection mold making process in our company: 

1. Products design department provides product information to injection mold design department, injection mold designers complete cost analysis in two working days, and provide to R&D manager. 

2. R&D department release "Mold Making Apply" to plastic injection mold design department after confirming the project.

Polyvinyl Chloride (PVC or Vinyl) is a high strength thermoplastic material widely used in applications, such as pipes, medical devices, wire and cable insulation...the list is endless. It is the world's third-most widely produced synthetic plastic polymer. 

Polyvinyl Chloride can be injection molded just like other plastics but the inclusion of chlorine in the material complicates the process. This is because melted PVC can give off a corrosive toxic gas. Accordingly,...

Prototype samples of plastic injection molding products are basic working samples, mockups, models, or just simulations of actual products, and other forms (final products and variants) are developed on this basis.

The main motivation for prototyping is to verify the design of the actual product. Sometimes, creating prototype samples is called implementation, because this is the first step in converting a virtual or conceptual design into an actual physical form.

It is a prelimina...

Polypropylene, abbreviated as PP, is a colorless, odorless, non-toxic, translucent solid substance. Polypropylene (PP) is a thermoplastic synthetic resin with excellent properties. It is a colorless, translucent, thermoplastic and lightweight general-purpose plastic. With chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high-abrasion processing properties, etc., this has made polypropylene quickly used in machinery, automob...

pom injection molding, Polyacetal, also known as acetal or polyoxymethylene (POM), is a formaldehyde-based, semi-crystalline engineering thermoplastic containing the functional group of a carbon bonded to two -OR groups. Other names of POM are Polyformaldehyde, Polymethylene glycol, Polyoxymethylene glycol. It is 100% recyclable.

POM resins are widely used in the production of precision plastic molding ...

PC is classified as a ''thermoplastic'', and the name has to do with the way the plastic responds to heat. Thermoplastic materials become liquid at their melting point (155 degrees Celsius in the case of Polycarbonat). A major useful attribute about thermoplastics is that they can be heated to their melting point, cooled, and reheated again without significant degradation. Instead of burning, thermoplastics is like Polycarbonate liquefy, which allows them to be easily injection molded and the...

Here we list some other materials for plastic injection molding parts.

PE, Polyethylene is a lightweight, durable thermoplastic with variable crystalline structure. It is one of the most widely produced plastics in the world. Polyethylene is used in applications ranging for films, tubes, plastic parts, laminates, etc. in several markets (packaging, automotive, electrical, etc.)

Polystyrene (PS) plastic is a naturally transparent thermoplastic that is ...

Nylon is commonly referred to using the chemical designation “PA” (e.g., PA 6 or PA 6/66) and is most widely available in black, white, and its natural color (off-white or beige). Perhaps the most common variant for engineering applications is Nylon 6/6. Nylon 6/6 can be extruded (melted and forced through a die) and is also a suitable plastic for both injection molding and 3D printing. It has a high melting temperature, making it an excellent substitute for metals in high-tempera...
