Español1. Cycle time:
The most effective way to reduce cycle time throughout the plastic chair production cycle is to shorten the cooling time. The temperature of the cooling water, the weight of the plastic chair, and the design of the water runner all affect the cycle time. So we will consider the runner type and the points of the runner to achieve the balance of mould cost and production cost.
2. Mould service life:
The hardness of the mould steel determines the service life of the plastic mould. At the same time, the accuracy of the plastic chair is guaranteed and defects are prevented. The high-quality mould steel has been processed many times, and the steel is chrome-plated to prevent the corrosion of the mould during the processing to affect the mould life.
3. Mould structure:
In the manufacturing process of plastic injection chair, the problem of insufficient material filling will occur. Mostly because the air in the mould cannot be exhausted, which makes the material unable to be filled.
Mould flow analysis can effectively avoid these product defects.
4. The parting line
There is a high requirement on the chair surface, so the parting line location is important. According to the sample or customer's thought, we will discuss the point of the parting line.
5. Wall thickness
6. Mould maintenance
During the continuous work of the mould, mould maintenance is required due to problems such as wear of parts, deterioration of lubricant, water leakage, and plastic material crushing during movement.
Mould maintenance is generally divided into daily maintenance and lower mould maintenance
The daily maintenance of the mould generally includes the following aspects:
* Regular rust removal (appearance, PL surface, cavity, core, etc.)
* Periodically re-lubricate (ejection mechanism, row position, etc.)
* Periodic replacement of wearing parts (rods, bolts, etc.)
* Other places to pay attention to
