What are the production and processing methods of Automotive Wiring Harness Protection Sleeve?

There are many ways to produce and process Automotive Wiring Harness Protection Sleeve. The processing methods are different, and the Automotive Wiring Harness Protection Sleeve produced are also different. The following editor will introduce several common production and processing methods for you.

1. Extrusion: depending on the type of polymer being processed and the shape of the finished or semi-finished product. Select the extruder, head and die, and then determine the extrusion process conditions, as well as the setting temperature and traction speed to extrude the product.
Extruded products include: Cable Sleeve, feeding bottle tubes, water pipes, special-shaped strips, high-pressure braided tubes, LED lamp sleeves, power tubes, insulating tubes, flame-retardant tubes, etc.
advantage:
① Can be infinitely long;
② There are very few waste products;
③The mold is cheap, the development cycle is short, and the output is high.
shortcoming:
①It can only be made into strips;
②The precision is low, and some shapes are difficult to produce.
2. Molding: It is a processing method of knitting sleeves that molds knitting sleeve raw materials into finished products by heating and pressurizing in a closed mold cavity. Usually, the powder sheet-shaped rubber block is first made into a blank similar to the finished product, placed in the cavity of a heated mold, and then closed and pressurized to form and solidify or vulcanize, and then demoulded to obtain Finished products, suitable for molding and processing of thermosetting products.
Molded products include: woven sleeve miscellaneous items, bracelets, mobile phone cases, cake dispensers, LED lamp plugs, etc.
advantage:
①It can be made into any shape;
② High precision, regular and beautiful product shape.
shortcoming:
① Only length less than 600mm can be made;
②There will be a lot of burrs and waste products;
③The cost of the mold is expensive, the development cycle is long, and the output is low.
3. Dip coating: After the Braided Sleeve is liquefied, the product surface is wrapped with the Braided Sleeve material by spraying or dipping.
Dip coating products include: high temperature wire, glass fiber tube, finger cot, etc.
shortcoming:
①It can only be used for painting with the same color, and it cannot be registered;
② The thickness of the coating film on the upper and lower parts of the object to be coated is uneven;
③Large solvent volatilization;
④ easy to pollute the environment;
⑤ The loss rate of paint is also relatively large.
4. Calendering: The product has a regular thickness and an infinite length through the extrusion molding process of the numerical control roller distance equipment.
Calendered products include: woven sleeve rolls, table mats, coasters, window grilles, etc.
5. Injection: The knitting sleeve material is injected into the mold through liquid or solid. The product can be the same as compression molding, but the properties of the product are different.
Injection products include: medical accessories, baby products, milk bottle nipples, auto parts, toy accessories, etc.
