Introduction to the Selection of Blowing Molding Dies

Don't solely focus on product design and neglect plastic mold manufacturing.
Some users, when developing new products or prototypes, often only focus on product development and research in the initial stages, neglecting communication with plastic mold manufacturers. There are two benefits to contacting mold manufacturers as soon as the preliminary design of the product is confirmed:
We guarantee that the designed products have excellent forming techniques, and the shaping design will not be modified due to difficulty in processing parts.
2. Mold manufacturers can prepare the design in advance to prevent hasty considerations that may affect the project timeline.
3. Produce high-quality plastic molds; close cooperation between both parties is essential to reduce costs and shorten the cycle.

Don't just focus on the price; consider quality, lead time, and service from multiple perspectives.
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 part material, physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, service life, and economy.
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 specialized molding requirements, necessitating advanced techniques such as hot runner molds, gas-assisted molding, and nitrogen cylinders.
4. Manufacturers should be equipped with CNC machines, electrical discharge machining (EDM) and wire-cutting machines, CNC profile milling equipment, high-precision grinding machines, high-precision three-coordinate measuring instruments, computer-aided design (CAD) and related software.
5. For general large stamping molds (such as automotive cover mold), consider whether the machine tool has a blanking edge device, even edge lubricant, and multi-position progressive feeding, etc. In addition to the stamping tonnage, also consider 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 collaborative manufacturer, it's crucial to understand their processing capabilities, not just by looking at hardware equipment, but also by considering 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 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 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 processing machinery for the 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 essential for a seamless, one-stop collaboration and to avoid multiple parties working separately. If the conditions aren't met, select one party to be responsible, and make sure to specify this clearly in the contract.
