Flexible customization and quick delivery

We adopt modular design concept and flexible production mode, which can quickly respond to the customized needs of customers. We can shorten the delivery period by 20%-30% on the premise of ensuring the quality, whether it is a small batch trial production or a large batch production, so as to help customers seize market opportunities.

Green manufacturing and sustainable development

We are committed to environmental protection and sustainable development, adopt low-energy equipment and environmentally-friendly materials, and optimize production processes to reduce carbon emissions. Our injection mold conforms to ISO 9001 environmental management system certification, helping customers achieve the goal of green production, while ensuring high performance and long life of products.

High-Quality Materials for Injection Molds

1. Acrylonitrile Butadiene Styrene (ABS)
This tough, impact-resistant plastic is widely used across industry. With good resistance to acids and bases, ABS also offers low shrinkage rates and high dimensional stability.
2. Polycarbonate (PC)
This strong, impact resistant plastic has low shrinkage and good dimensional stability. A transparent plastic that is available in different optically clear grades, PC can provide a high cosmetic finish and good heat resistance.
3. Aliphatic Polyamides (PPA)
There are many different types of PPA (or nylons), each of which has its own advantages. Generally-speaking, nylons offer high strength and temperature resistance as well as being chemically resistant, apart from against strong acids and bases. Some nylons are abrasion resistant and offer good hardness and stiffness with good impact strength.
4. Polyoxymethylene (POM)
Commonly known as acetal, this plastic has high hardness, stiffness, strength and toughness. It also has good lubricity and is resistant to hydrocarbons and organic solvents. Good elasticity and slipperiness also provide advantages for some applications.
5. Polymethyl Methacrylate (PMMA)
PMMA, also known as acrylic, provides good optical properties, high gloss and scratch resistance. It also offers low shrinkage and less sink for geometries with thin and think sections.
6. Polypropylene (PP)
This inexpensive resin material delivers high impact resistance in certain grades but can be brittle in cold temperatures (in the case of propylene homopolymer). Copolymers offer greater resistance to impact while PP is also wear-resistant, flexible and can provide very high elongation, as well as being resistant to acids and bases.
7. Polybutylene Terephthalate (PBT)
Good electrical properties makes PBT ideal for power components as well as automotive applications. The strength ranges from moderate to high depending on glass fill, with unfilled grades being tough and flexible. PBT also shows fuels, oils, fats and many solvents, and it also doesn’t absorb flavours.

8. Polyphenylsulfone (PPSU)
A dimensionally stable material with high toughness, temperature and heat resistance, PPSU is also resistant to radiation sterilisation, alkalis and weak acids.
9. Polyether Ether Ketone (PEEK)
This high temperature, high-performance resin provides heat resistance and flame retardancy, excellent strength and dimensional stability, as well as good chemical resistance.
10. Polyetherimide (PEI)
PEI (or Ultem) offers high temperature resistance and flame retardancy, along with excellent strength, dimensional stability and chemical resistance.

Chemical properties:
Chemical corrosion resistance: it has good tolerance to acid, alkali and salt, but some chemical solvents may cause corrosion to it.
Flame retardancy: By mixing with PVC, its flame retardancy can be significantly improved, reaching the highest level of UL94-5VA 4.

Electrical performance:
Insulation performance: it has good insulation performance, is not easy to conduct electricity, and is stable in high temperature environment.
Processing performance:
Machinability: various products can be made by injection molding, extrusion and other processes, which is suitable for manufacturing thin-walled and thick parts 35.
