What are the main issues to keep in mind during mold production?
Only focus on product design and ignore mold production-(plastic bag punching machine, pneumatic punching machine, plastic bag punching machine, bag making machine punching machine).
How to take the stubborn finished product left in the mold
If you take the stubborn finished product left in the mold 1, use a brass sheet to squeeze it into the crack between the finished product and the mold, pry the finished product away from the cavity, but apply this method to the non-ferrous alloy mold. 2. In order to achieve this goal, the injection molding machine should be equipped with a brass sheet (for example, a 3MM thick, 300MM wide, brass blade molded at the front end) mold new technology. The research and development and application of new mold technology are developed in the future The bias of new mold technology, the development and application of new mold technology is today …
When some users are developing products or trial production of new products, they often only focus on product development and development at the initial stage, neglecting to communicate with the mold making unit. After the product design plan is initially determined, there are two advantages to contacting the mold manufacturer in advance:
1. The product that can be guaranteed has a good forming process, and will not be designed by points because of the difficulty in processing the parts.
Second, the mold maker can do design preparation in advance to prevent inadequate consideration in a hurry and affect the construction period.
In short, to produce high-quality molds, only when supply and demand are carefully joint ventures, will it be possible to reduce the cost and cycle time.
Don’t just look at the cost, we must consider all aspects of quality, cycle and service-plastic bag punching machine, pneumatic punching machine, plastic bag punching machine, bag making machine punching machine.
There are many types of molds, which can be divided into ten categories. According to the different requirements of parts materials, physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, application life, economy, etc., select different examples of mold forming.
High-precision molds must be processed with high-precision CNC machine tools, and the mold materials and forming processes have strict requirements. CAD / CAE / CAM mold technology must also be used to design and elucidate. Some parts have special requirements for molding, and the mold also needs to apply excellent processes such as hot runners, gas-assisted molding, and nitrogen cylinders. The production plant should have CNC, EDM, wire cutting machine tools and CNC profile milling buildings, high-precision grinding machines, high-precision three-coordinate measuring instruments, computer design and associated software. Ordinary large stamping dies (such as automobile cover parts dies) should consider whether the machine tool has a blank holder mechanism, even edge lubricant, multi-station progressive, etc. In addition to stamping tonnage, it is also necessary to consider punching times, feed assembly, machine tool and die guard assembly.
