Successful injection molding depends on the machine's ability to operate the molded parts and the materials used under the correct pressure, temperature and operating speed conditions. It also depends on the ability to keep operating conditions close to limits for a long time, and the ability to accurately repeat the operating cycle thousands or ... read more
1.cooling, washing and lubrication, keep cooling and lubrication clean, control the grinding heat within the allowable range, and prevent thermal deformation of the workpiece. Improve the cooling conditions during grinding, such as the use of sinking wheels or internal cooling wheels. The cutting fluid is introduced into the center of the grindin... read more
In order to eliminate the secondary operation of demolding, injection molds have been developed that automatically demold the parts from the runner system through the opening movement of the mold. Self-degassing principle Self demolding requires two parting lines in the mold. On the first parting line, the melt is distributed fr... read more
In addition to the time (in hours) required to manufacture tools for a given plastic part, material items, tool maintenance and amortization are also included in estimates. It must also include the indirect costs of maintaining the tools. The cost of die steel is usually proportional to the labor involved. But it should be estim... read more
The cost estimation of plastic molding needs to consider several factors. These factors can be listed as follows: 1. Mold cost estimation. 2. Cost estimation of plastic materials and other raw materials. 3. Estimate manufacturing operations. 4. A summary of cost factors in a standard... read more
