Cable wire harness processing products account for the main raw materials. Wire harness companies require quality assurance for suppliers' selection and requirements, and wire bundle processing plants must understand the quality standards of wires and the raw materials used to evaluate cable manufacturer's quotation. 

Raw USB wire processing plant raw material analysis

First, the rubber material generally has PVC, PE, PP and other materials. According to different characteristics, wire manufacturers generally choose PVC that is not easy to burn, aging resistant and oil resistant as the outer cover of the cable.

1. PVC (polyvinyl chloride) has the characteristics of being non-flammable, aging-resistant, oil-resistant, chemical-resistant, impact-resistant and easy to color. Therefore, wire processing plants generally choose PVC as the insulation sheath of wire and cable.  However, due to its large dielectric constant, it is generally used only as an insulating material for low-voltage cables and as an insulating material for control cables. The lowest operating temperature is -40 degrees and the highest temperature is up to 105 degrees.

2. PE (polyethylene) processing melting range is 132~1350 °C, ignition temperature is 3400 °C, self-ignition temperature: 3900 °C, so PE is usually used as the material for forming inner film during wire harness processing.

3. PP (polypropylene) has excellent mechanical strength, softening temperature is the highest in thermoplastics, low temperature resistance, and aging resistance. Generally, wire harness processing plants use a small amount of outer molding.

Second, the conductor main cable transmission signal, according to different metal characteristics, usually bare copper wire, tinned copper wire, silver plated copper wire, etc., according to the type of wire, the proportion of metal conductors are different, of which copper wire  The proportion of the wire cost is the largest, so the cost price of the wire will vary with the price of copper.

In the cable inspection, the wire harness processing manufacturer must strictly test the specifications of the conductor and the material of the outer casing. The sinodec industrial co., ltd. is a USB cable manufacturer of 16 years, we always choose the reliable wire harnesses  factory as our suppliers and provide high quality of USB cable as per customer's requirement.
