Several issues should be paid attention to in the design and manufacture of injection molds
1). don't just focus on product design and ignore the manufacturing of injection molds:
When developing products or new products, some users tend to focus on product development and ignore communication with ABS injection mold production units. After the product design plan is initially determined, there are three benefits to contacting the injection mold supplier in advance:
1. It can ensure that the designed product has a good molding process and will not change the finalized design, because this part is difficult to process.
2. Injection mold manufacturers can make design preparations in advance to prevent hasty inconsistencies and affect the construction period.
3. To produce high-quality injection molds, only close cooperation between supply and demand can reduce costs and shorten the cycle.

2). don't just look at the price, you must consider all aspects such as quality, cycle, and service:
1. There are many types of injection molds, which can be roughly divided into ten categories. According to the different requirements of the part material, different types of TPU injection molds are selected for molding in terms of physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, service life, and economy.
2. High-precision injection molds require high-precision CNC machine processing, and have strict requirements on injection mold materials and molding processes. Design analysis also requires CAD/CAE/CAM injection mold technology.
3. Some parts have special requirements for molding, and injection molds also require advanced processes such as hot runners, gas-assisted molding, and nitrogen bottles.
4. Manufacturers should have CNC, EDM, wire cutting and CNC profiling milling equipment, high-precision grinders, high-precision three-coordinate measuring instruments, computer design and related software.
5. For general large-scale stamping injection molds (such as automobile hood injection molds), it is necessary to consider whether the machine has a crimping mechanism, whether it has lubricants, and whether it has a multi-station level. In addition to the stamping tonnage, the protective devices of the stamping, feeding device, machine tool and injection mold should also be considered.
6. The manufacturing methods and processes of the above-mentioned injection molds are not owned and mastered by every enterprise. When choosing a cooperative manufacturer, it is necessary to understand its processing capabilities, not only considering the hardware equipment, but also combining the management level, processing experience, and technical strength.
7. For the same PC injection mold, different manufacturers sometimes have a big difference. You should not pay more than the value of the injection mold, nor should you pay less than the cost of the injection mold. Like you, injection mold manufacturers must make a reasonable profit in their business. It may be troublesome to order a set of injection molds at a much lower quote. Users must start from their own needs and make a comprehensive assessment.
3). Avoid multi-head cooperation and try one-stop production of injection molds and product processing:
1. It is not necessarily possible to produce batches of qualified products through qualified injection molds (qualified test pieces). This mainly involves the selection of parts, molding process (molding temperature, molding time, etc.) and the technical quality of operators.
2. Have good injection molds, good molding processes, can work together, and try to avoid long-term cooperation.
