Plastic products should not only focus on product design, but also neglect plastic mold manufacturing
Most users, when developing products or new plastic products, often focus only on the research and development of plastic products in the early stages, neglecting cooperation and communication with plastic mold processing units. Plastic product design scheme
After preliminary confirmation, it is necessary to collaborate and communicate with the mold manufacturer in advance
1、 The early development benefits of plastic products
1. It can ensure that the designed product has good forming technology and will not be modified due to the difficulty of machining the parts.
2. The mold maker can make design preparations in advance to prevent hasty and thoughtless considerations that may affect the project schedule.
3. Making high-quality plastic molds requires close cooperation between supply and demand in order to ultimately reduce costs and shorten the cycle.
2、 In the later stage of plastic mold processing, do not only consider the price, but also consider quality, cycle, and service from all aspects.
1. There are many types of molds, which can be roughly divided into ten categories. Select different types of molds for forming based on different requirements such as part materials, physical properties, mechanical strength, dimensional accuracy, surface smoothness, service life, and economy.
2. High precision plastic molds require the use of high-precision CNC machine tools for processing, and there are strict requirements for mold materials and forming processes. CAD/CAE/CAM mold technology is also required for design and analysis.
3. Some parts require advanced processes such as hot runner, gas assisted molding, and nitrogen cylinder for plastic molds due to special requirements during molding.
4. Plastic mold manufacturers should have CNC, EDM, wire cutting machines and CNC profile milling equipment, high-precision grinding machines, high-precision three coordinate measuring instruments, computer design and related software, etc.
5. Generally, large stamping molds (such as automotive cover parts molds) need to consider whether the machine tool has an edge pressing mechanism, even edge lubricants, multi station progressive, etc. In addition to stamping tonnage, considerations should also be given to punching times, feeding devices, machine tools, and mold protection devices.
6. The manufacturing methods and processes of the above-mentioned molds are not possessed and mastered by every enterprise. When choosing a collaborative manufacturer, it is important to understand its processing capabilities, not only based on hardware equipment, but also on management level, processing experience, and technical strength.
7. There may be significant differences in quotes from different manufacturers for the same set of plastic molds. You should not pay more than the value of the mold, nor should you pay less than the cost of the mold. Mold manufacturers, like you, need to achieve reasonable profits in their business. Customizing a much lower priced mold would be the beginning of trouble. Users must start from their own requirements and comprehensively evaluate.
