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 early stages, neglecting communication with plastic mold manufacturers. There are two benefits to contacting mold manufacturers before the initial design of the product is finalized:
1. We guarantee the products are designed with excellent forming techniques, ensuring the original design is not altered due to 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 manufacturing requires close collaboration between both parties to reduce costs and shorten lead times.

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 chosen 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 materials and forming processes. CAD/CAE/CAM mold technology must also be used for design and analysis.
3. Certain 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 profile 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 if the machine tool has a blanking edge device, even 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 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 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 at a much lower price could be the start of trouble. Users must weigh their requirements from their own perspective.

Avoid multiple collaborations; strive for a one-stop service for plastic mold making and product processing.
1. Having a qualified mold (sample is qualified) does not necessarily mean you can produce a batch of qualified products. This mainly relates to the selection of processing machinery for parts, 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 a one-stop collaboration process, aiming to minimize multiple collaborations. If the conditions aren't met, choose one party to be responsible, and make sure it's clearly stated in the contract.
