Introduction to the Selection of Blowing Molding Dies
Don't solely focus on product design and neglect the plastic mold manufacturing.
Users often focus solely on product development and prototyping in the initial stages, neglecting communication with plastic mold manufacturers. There are two benefits to contacting mold manufacturers prior to the preliminary confirmation of the product design:
1. We guarantee the products are designed with excellent forming techniques, ensuring the final design is not altered due to the difficulty in processing parts.
2. Molding manufacturers can make design preparations in advance to prevent hasty considerations that may affect the project timeline.
3. To produce high-quality plastic molds, close collaboration between both suppliers and buyers is essential for cost reduction and cycle shortening.
Don't just focus on price; consider quality, lead time, and service from multiple angles.
1. There are many types of molds, which can be roughly divided into ten categories. Different mold forming types are selected based on various requirements such as part 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 process. CAD/CAE/CAM mold technology is also necessary for design and analysis.
3. Some parts require special molding requirements, necessitating advanced techniques such as hot runner molds, gas-assisted molding, nitrogen cylinders, and other sophisticated processes.
4. Manufacturers should possess CNC machines, 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 pressing edge mechanism, as well as side lubricants, multi-station progressive feeding, etc. In addition to the stamping tonnage, also take into account the number of strokes, feeding device, machine tool, and mold protection devices.
6. The manufacturing methods and processes for the aforementioned molds are not possessed or mastered by every company. When selecting a collaborative manufacturer, it's crucial to understand their processing capabilities, not just the hardware equipment, but also their 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 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 price can be the start of trouble. Users must weigh their own requirements.
Avoid multiple collaborations; strive for a one-stop service in plastic mold making and product processing.
1. Having a qualified mold (sample passes) does not necessarily guarantee the production of bulk qualified products. This primarily relates to the selection of machine tools for part processing, forming technology (forming temperature, forming time, etc.), and the operator's technical qualifications.
2. With a good mold, there must also be quality forming processing. It's essential for a seamless collaboration, minimizing redundant efforts. If conditions aren't met, select one party to be responsible, and make sure to clarify this in the contract.
