Introduction to the Selection of Blowing Molding Dies
Don't solely focus on product design and neglect plastic mold manufacturing.
Many users, when developing products or prototypes, often initially focus solely on product development and research, neglecting communication with plastic mold manufacturers. There are two benefits to contacting mold manufacturers early after the preliminary design of the product is determined:
1. We guarantee that the designed products have excellent forming processes and the design will not be altered due to difficulty in part processing.
2. Molding manufacturers can prepare the design in advance to prevent hasty considerations that could affect the project timeline.
3. Produce high-quality plastic molds; only with close collaboration between both supply and demand parties can costs be reduced and the cycle shortened.
Don't just focus on price; consider quality, cycle time, and service from multiple angles.
There are many types of molds, which can be roughly divided into ten categories. Different types of molds are chosen for forming based on various requirements such as material, physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, service life, and cost-effectiveness.
2. High-precision molds require machining on high-precision CNC machines, and there are strict requirements for mold material and forming processes. CAD/CAE/CAM mold technology is also needed for design and analysis.
3. Some parts require special molding requirements, necessitating advanced techniques such as hot runner molds, gas-assisted molding, nitrogen cylinders, etc.
4. Manufacturers should possess CNC, EDM, wire-cutting machines, CNC profile milling equipment, high-precision grinding machines, high-precision three-axis measuring instruments, computer design and related software.
5. For general large-scale stamping molds (such as automotive cover molds), consider whether the machine tool has a blanking edge mechanism, as well as edge lubricants, multi-position progressive feeding, etc. In addition to the stamping tonnage, also consider the number of strokes, feeding device, machine tool, and mold protection devices.
6. The manufacturing methods and techniques for the aforementioned molds are not possessed or mastered by every enterprise. When selecting a collaborative manufacturer, it is crucial to understand their processing capabilities, not only by examining hardware equipment but also by combining management levels, processing experience, and technical strength.
7. There can be significant differences in quotes for the same mold from different manufacturers. You shouldn't pay more than the mold's value, nor should you pay less than its cost. Mold manufacturers, like you, need to make a reasonable profit in their business. Ordering a mold with a much lower quote can be the start of trouble. Users must assess based on their own requirements.
Avoid fragmented collaboration and strive for a one-stop service in plastic mold making and product processing.
1. Having a qualified mold (sample passes) does not guarantee the production of batch-qualified products. This mainly depends on the selection of the machine tool for part processing, forming process (forming temperature, forming time, etc.), and the operator's technical qualifications.
2. With a good mold, a high-quality forming process is essential; it should be a seamless collaboration. Try to avoid multiple collaborations if possible. If conditions aren't met, choose one party to be responsible, and make sure to specify this in the contract.
