What problems will silicone products encounter during the production process？

Vtop Manufacturing Solution

1. Stripes and dark lines

Reason: Uneven mixing during the rubber refining process, and short mixing time when adding vulcanizing agents and colorants, resulting in uneven color. Improper temperature control during the molding process can also lead to stripes and dark lines.

Solution: Ensure even mixing during the rubber refining process, and control the addition time of vulcanizing agent and colorant. Pay attention to temperature adjustment during molding to ensure that the temperature is moderate.

2. Shortage and repair

Reason: Failure to replenish materials in a timely manner or insufficient replenishment during molding, resulting in a shortage of materials in the product.

Solution: Timely replenish materials to ensure sufficient supply of raw materials. Products with minor material shortages can be repaired, while products with severe material shortages need to be scrapped.

3. Bubbles and bulges

Reason: There are problems in the raw materials, machinery, manual operation, and mold structure, such as poor exhaust of the machinery and uneven mold temperature.

Solution: Check the exhaust system of the machine and mold to ensure uniform temperature. Control the placement of raw materials and the method of rubber mixing.

4‌. Material burnt to death

Reason: During high-temperature operations, the material was placed into the mold at a too slow speed, resulting in the rubber material being burned to death.

Solution: Increase the operating speed and quickly put the material into the mold for solidification. Control the mold temperature well to avoid excessive temperature.

5. Cloak and split edge explosion

Reason: The mold parting line has significant wear and tear, and the hardness of the raw materials is not suitable.

Solution: Use high-quality steel to enhance the service life of the mold and control the hardness of the raw materials.

6. Dimensional issues

Reason: Improper mold design, inaccurate process control, or uneven raw material ratio.

Solution: Optimize mold design, precisely control process parameters, and ensure uniform raw material ratio.

7. Flyedge thickening

Reason: Unreasonable mold design, excessive gap between parting surfaces, or improper pressure control.

Solution: Improve mold design, control the gap and pressure of the parting surface.

8. Cracks

Reason: Improper mold design or process control leading to product rupture.

Solution: Optimize mold design and process control to avoid product breakage.

9. Vulcanizing agent issue

Reason: Improper selection of vulcanizing agent affects product performance.

Solution: Select the appropriate vulcanizing agent according to product requirements to ensure stable product performance.

10. Raw material issues

Reason: Improper selection of raw materials affects the toughness and tensile strength of the product.

Solution: Select appropriate raw materials based on product requirements to ensure product performance.

Through the above measures, problems in the production process of silicone products can be effectively reduced, and product quality and production efficiency can be improved.
