Introduction to the Selection of Blowing Molding Dies
Don't solely focus on product design and neglect the plastic mold manufacturing.
Some users, when developing products or new product prototypes, often only focus on product research and development at the initial stage, neglecting communication with plastic mold manufacturing units. There are two benefits to contacting mold manufacturers as soon as the preliminary design of the product is determined:
We guarantee that the designed products have excellent forming techniques and the final design will not be altered due to difficulty in processing parts.
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 with close cooperation between both supply and demand parties can costs be reduced and cycles shortened.
Don't just focus on price; consider quality, cycle, and service from multiple angles.
1. There are many types of molds, generally categorized into ten main types. Different mold forming types are selected based on varying 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 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, electrical discharge machining (EDM) and 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 car cover molds), consider whether the machine tool has a blanking edge mechanism, even edge lubricants, and multi-position progressive operations. 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 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 their management level, processing experience, and technical strength.
7. There can be significant differences in quotes for the same mold from different manufacturers. You should not 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 fragmented collaboration; 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 bulk 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, you also need excellent forming processing. It's essential for a seamless collaboration, avoiding multiple parties as much as possible. If the conditions aren't met, choose one party to be responsible, and make sure to clearly state this in the contract.
