Press Brake

For sheet metal bending, the press brake is a necessary machine. We have NC type and CNC type press brakes. At the same time, we can customize the punches and dies according to your practical use in sheet metal fabrication.

Shearing Machine

For the straight cutting of steel plate, hydraulic shearing machine is a good choice. It not only has high cutting efficiency, but also requires less investment. We have both swing beam shears and guillotine shears for your selection.

Laser Cutting Machine

In the current metal plate and pipe cutting, laser cutting machine is undoubtedly the best choice. It can not only cut various shapes, but also has small cutting gap, high precision and high cutting efficiency. Today, it is very cost-effective.

8 Most Commonly Used Non-Metallic Materials In Non-Standard Machinery

1. POM

POM

POM is the most commonly used material in non-standard machinery.

The surface of this material is relatively lubricating and wear-resistant. It can be used continuously at – 40 ° to 100 ℃.

The processing size is good, and the working accuracy can be guaranteed within 0.03mm at a constant temperature.

It is generally used for lightweight shaft or gear and other parts.

2. PTEF

PTEF

English abbreviation (PTFE), also known as plastic king, Teflon, is a polymer material.

It is very resistant to high and low temperatures and can reach – 180 ℃ to 260 ℃.

The friction coefficient is very low. The friction with steel materials can reach 0.04, which is close to rolling friction.

It is also one of the most corrosion-resistant materials in the world. It can resist any organic solution.

The material is relatively soft, difficult to process and easy to deform, so it is unable to process high-precision parts.

It is generally used for wear-resistant parts in mechanical design, such as chain guide rail, W-type sealing ring, etc.

3. Nylon

Nylon

Nylon is one of the more materials used in non-standard machinery. It is wear-resistant and self-lubricating.

It can beat the lubricating oil at high temperature to make its friction coefficient very low. The material has high geometric accuracy and can process gear bearings and other parts.

High temperature resistance can reach 160 ℃ for continuous use, but soaking in water is easy to absorb water and expand, resulting in accuracy impact.

4. PVC

PVC

The name is polyethylene. This material is cheap and widely used. It is also one of the materials commonly used in non-standard machinery.

PVC has anti-static and non-static materials. In electronic products, and the belt used is anti-static. There is also a difference between PVC hard materials and soft materials.

Generally, hard materials, such as tooling board, bear the load. The melting point of the material is 75-90℃.

The product cannot be used in contact with food because high temperatures will release carcinogens.

5. Polyurethane

Polyurethane

Pu, also known as Youli adhesive, has good oil resistance, toughness, wear resistance, aging resistance and adhesion;

It has the rigidity of plastic and the elasticity of rubber. Specialized for industrial use (PU);

Wheel, forklift wheel, sliding plate wheel, cigarette maker wheel, bearing wheel, driving wheel, etc;

Polyurethane is generally used for silencing layer, seal, buffer head, buffer, anti scratch part, anti scratch part, fixture cushion block and lightweight cushion.

6. ABS

ABS

ABS plastic is a resin made of three monomers, A (acrylonitrile) B (butadiene) S (styrene), which can be made into various resins with different contents.

It is suitable for general parts, wear-resistant parts and transmission parts in machinery.

ABS is also one of the main materials for 3D printing and the most stable material in 3D printing.

7. Rubber

Rubber

It refers to the high elastic polymer material with reversible deformation. Increasing the friction coefficient on the surface of the drum in machinery is the rubber coated rubber, which has high wear resistance and good sealing performance.

Rubber is used for oil seal and O-ring. However, the rubber will age, generally cracking and hardening.

8. Bakelite

Bakelite

Chemical name: phenolic plastic, which has high mechanical strength and good wear resistance. There are anti-static and non-static in the selection.

It can be used for tooling board, fixture base plate and lightweight material, but its mechanical performance is poor and its precision after processing is not high.

Therefore, it can not be used in occasions with large load and high precision.
