What is the difference between molded and extruded Automotive Wiring Harness Protection Sleeve?

Regarding the molded Automotive Wiring Harness Protection Sleeve and the extruded Automotive Wiring Harness Protection Sleeve, many people don't know the difference between them, what are their advantages and disadvantages, so they don't know which one to choose when choosing. The following editor will introduce the differences between them for you.

Molding: Generally, the powder sheet-shaped Cable Sleeve is first made into a blank with a shape similar to the product, and placed in the cavity of a heated mold, and then the mold is closed and pressed to make it molded and cured or vulcanized, and then removed Molded products, this method is especially suitable for the molding and processing of thermosetting products. In short, molding is a Cable Sleeve processing method in which the Cable Sleeve is formed into a finished product by means of heating and pressure in a closed mold cavity.
advantage:
①It can be made into any shape;
② High precision, regular and beautiful product shape;
shortcoming:
① Generally, only lengths less than 600 mm can be made;
②Long production cycle and low efficiency;
③The production process will produce a lot of burrs and waste products;
④ The cost of the mold is expensive and the development cycle is long;
⑤The length is limited by the vulcanized plate;
Extrusion: Generally, according to the type of polymer to be processed and the shape of the product or semi-finished product, select the extruder, head and die, as well as the corresponding auxiliary devices such as shaping and traction, and then determine the extrusion process conditions such as screw speed, Machine head pressure, material temperature, setting temperature, traction speed, etc. In the extrusion process, the material is generally plasticized, but the shaping method is different. The semi-finished products extruded from the Braided Sleeve need further vulcanization.
advantage:
①It can be wireless long;
② Fast production cycle and high capacity;
③ Few waste products are generated;
④The mold is cheap, and the development is convenient and fast;
shortcoming:
① Dimensional tolerance is too large;
②It can only be made into strips;
In terms of cost and speed, extruded products and molded products of Braided Sleeve should be extruded, because molded products are more expensive than extruded products. Extrusion is generally used for Automotive Wiring Harness Protection Sleeve. Molding is generally used for very precise miscellaneous parts.
