Generally, there is a process of starting up and adjusting the mold when producing silicone hose. This process is mainly to ensure the product quality of silicone hose. However, when some customers order silicone hose, they always feel that it is unreasonable for us to charge them the start-up fee. In fact, the silicone hose manufacturers charge the start-up fee because the process of start-up and mold adjustment is very wasteful of materials, so the silicone hose manufacturers will respond. The customer charges a startup fee to start the mold adjustment to ensure the quality of the product, because the surface of the silicone hose produced without the mold adjustment process generally has honeycomb holes, so what causes these honeycomb holes?

 

First of all, the reasons for the rough surface, cracks and honeycomb holes of the silicone tube are generally as follows:
1. It may be due to insufficient sulfur pressure.
2. The vulcanization time is not enough.
3. The amount of natural rubber is insufficient.
Secondly, how to solve the above-mentioned problems?
1. Insufficient sulphur pressure: You can try to press and exhaust several times.
2. Insufficient vulcanization time: the vulcanization time can be increased appropriately.
3. Insufficient amount of natural rubber: increase the weight of the rubber.

In short: the reasons for the honeycomb holes on the surface of silicone hose products are the above three. In addition, there are "honeycomb holes" on the surface of the silicone hose. It is recommended to cut the silicone tube to see if the rubber contains water or pores? If there is a description, it may be due to insufficient pressure due to lack of glue. If not, consider whether the mold temperature is too high to burn the surface.
