Is it more difficult to open the mold for the larger the size of the Automotive Wiring Harness Protection Sleeve?

In daily life, small-sized Automotive Wiring Harness Protection Sleeve can be seen everywhere, and some large-sized Automotive Wiring Harness Protection Sleeve with a diameter of thirty to forty or forty or fifty are also useful. Some people will ask that such a large specification can control the size during production Does the product meet the requirements? The following editor will solve this doubt for everyone.

Since the product is a problem during production, we still have to go back to the production line to find the reason. First, check whether the tear strength of the raw material meets the standard. Note: After compounding the rubber, extruding the Automotive Wiring Harness Protection Sleeve during the molding process, the temperature is too high or the time is too long, which will cause the product to become brittle; if there is no problem with the raw materials, the molding operation has also controlled the temperature and vulcanization time. The protective cover is still prone to brittleness, which is likely to be a problem with the mold. If the structural design of the mold is unreasonable, the product produced will not work if some parts are thin and some parts are thick. In short, to make a standard Cable Sleeve product requires the cooperation of many aspects, and the operation of technicians is also very important.
First of all, the extruded Automotive Wiring Harness Protection Sleeve will be fed, passed through the mold, baked at high temperature, and finally formed. During this period, the size of the tube will vary with the change of temperature and time. This requires the front and rear operators to control the tolerance range at any time, If the normal diameter is below 5MM, the standard of the industry standard is a range of plus or minus 0.1MM. If the inner and outer diameters are between 5-10MM, there will be a standard of plus or minus 0.15MM.
It can be seen that the larger the size of the Automotive Wiring Harness Protection Sleeve does not mean that the mold cannot be opened, but the tolerance will increase accordingly with the increase in size. Generally, as long as the diameter of the automotive wiring harness protective cover is less than 100, there is no problem in mold opening, but it should be noted that the quality of the mold must be closed, because the mold directly affects the quality of the large-scale products, and will also affect the overall production. efficiency.
