Introduction to the Selection of Blowing Molding Dies

Don't solely focus on product design, neglecting the 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 well before the preliminary design of the product is finalized:
We guarantee the products have good forming techniques, and the design will not be altered due to difficulties in part processing.
2. Mold manufacturers can prepare the design in advance to prevent hasty considerations that could affect the project timeline.
3. Produce high-quality plastic molds; only through close collaboration between both supply and demand parties can costs be reduced and cycles shortened.

Don't just focus on price; consider quality, cycle time, and service from multiple aspects.
1. There are many types of molds, which can be roughly divided into ten categories. Different mold types are selected for forming based on various requirements such as material of the parts, 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 specialized molding requirements, necessitating advanced techniques such as hot runner molds, gas-assisted molding, nitrogen cylinders, and other cutting-edge processes.
4. Manufacturers should be equipped with CNC machines, EDM, wire-cutting machines, and CNC profiling milling equipment, high-precision grinding machines, high-precision three-axis measuring instruments, computer design and related software.
5. For general large stamping molds (such as automotive cover mold), consider whether the machine tool has a blanking edge mechanism, as well as edge lubricant, multi-position progressive feeding, etc. In addition to the stamping tonnage, also take into account the stroke, feeding device, machine tool, and mold protection device.
6. The manufacturing methods and processes for the aforementioned molds are not possessed or mastered by every company. When selecting a collaborating manufacturer, it is crucial to understand their processing capabilities, not just the hardware equipment but also the management level, processing experience, and technical strength.
7. There can be significant price differences for the same mold from different manufacturers. You shouldn't pay more than the mold's value nor less than its cost. Mold manufacturers, like you, need to achieve a reasonable profit in business. Ordering a mold with a much lower quote can be the start of trouble. Users must weigh their own requirements.

Avoid multiple collaborations; strive for a one-stop service from plastic mold making to product processing.
1. Having a qualified mold (sample qualified) does not necessarily guarantee the production of batch-qualified products. This primarily relates to the selection of machine tools for part processing, forming technology (forming temperature, forming time, etc.), and the technical qualifications of the operator.
2. With a good mold, good forming processing is also necessary. It should be a seamless collaboration, avoiding multiple parties as much as possible. If the conditions are not met, choose one party to be responsible, and make sure to clearly state this in the contract.
