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 manufacturers. There are two benefits to contacting mold manufacturers as soon as the preliminary design of the product is determined:
1. We guarantee that the products we design have excellent forming techniques and the design will not be altered due to the difficulty in processing parts.
2. Molding manufacturers can prepare the design in advance to prevent hasty consideration and affect the project timeline.
3. High-quality plastic mold production can only reduce costs and shorten cycles with close cooperation between both parties in supply and demand.
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 materials and forming processes. CAD/CAE/CAM mold technology must also be used 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 be equipped with CNC machines, EDM, wire-cutting machines, 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 car cover molds), consider if the machine tool has a flanging mechanism, as well as side lubricants and multi-station progressive operations. In addition to the stamping tonnage, also take into account the number of strokes, 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 their management level, 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 from their own requirements.
Avoid multiple collaborations; strive for a one-stop service for plastic mold making and 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, you also need excellent forming processing. It's all about 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.
