How is the USB data line formed?

Usually, USB data cables are commonly used in PVC and TPE materials. When the moisture content is higher than a certain amount during extrusion processing, the extruded products will have rough surface, bubbles and cross-section holes. When the water content exceeds about 0.05%, Expropriated products may be subject to poor appeal. In order to improve the quality of products, plastics must be dried after 70-75 degrees and 2-4 hours of drying before production.

1. The process of injection molding

Clamping -----Clamping----Shooting -----Pressure-keeping--Cooling--Feeding-------Opening-------Demolition (Removal product)

2. Molding operation instructions:

1. Before closing the mold: The mold strip must be placed in the mold fixing pin; the terminal of the USB data cable is inserted in place (preventing the short leg); the cycloid is centered (not up-down, left-right, or left-right); confirm whether the nozzle is removed; Before moulding, remember that the direction cannot be reversed. The mould is typed and the word is correct.

2. Before opening the mold: Press the wire to prevent it from sticking.

3. During the operation, pay attention to the hopper, and feed it in time when the material is used up quickly.

4. Without permission, it is not allowed to adjust machine or remove mould.

5. Copper plug, pay attention to the copper pop-up insert. Insert three pieces of beer before inserting the copper piece, take the plug after molding, and gently tap and take care to scratch the copper piece.

USB data cable

USB data line molding quality requirements:

1. The exposed size of the plug hardware is accurate and the terminals are not scratched or deformed.

2. The plastic part of the plug has no appearance such as shrinkage, noise, watermark, batch peak, blistering, etc.

3. There is no front-end or crack in the combined parts of the plug hardware and injection molding.

4. The root of the net is free of pressure, plastic, scratched wire, wicking, leaking copper, etc.

5 plug nameplate: according to product drawings

USB data line molding specifications:

1. During the operation, it is necessary to clamp the hands in two hands. During the mold clamping process, it is forbidden to reach into the mold.

2. Do not operate the same machine for two

3. At the beginning of each shift, check the emergency switch, mold switch, and temperature controller of the machine.

4. Before work, clean the working area of the machine and keep the distribution box of the machine clean.

Special case:

Why do some customers require glue or syrup when molding SR=tail cards?

Objective: To increase the adhesion between the SR and the outer layer of the electric wire, and to increase the pulling force of the SR and the wire outer cover.
