Are molds getting worse and experiencing dimensional drift with use? 5 core details to maintain long-term mass production accuracy of molds
Many plastic molds share a common problem: while the new mold performs perfectly during testing, its precision gradually declines after several thousand molds are produced in mass production
Deepening and upgrading technology | Hongyunyuan Electronics precisely empowers the precision molding and mass production track of medical devices
Hongyunyuan Electronics will continue to focus on three core sectors: medical devices, consumer electronics, and automotive new energy. We will continuously iterate on precision manufacturing processes, upgrade our quality control system, and provide our customers with cost-effective precision molding solutions through more professional technology, more efficient delivery, and more compliant production standards
Why are other people's molds durable and cost-effective, despite using the same mold-making process? 80% of buyers have fallen into the pitfall of low prices
When it comes to purchasing plastic molds, many people have encountered such confusion:Despite the apparent similarity in mold appearance and dimensional parameters between two apparently similar molds, the price difference can be thousands or even tens of thousands. Choosing the cheaper one often leads to frequent issues during mold testing, burrs, shrinkage, and warping during mass production, resulting in mounting mold modification costs in the later stages. On the other hand, choosing the more expensive one raises concerns about exceeding the budget and being questioned for the premium price. In fact, plastic molds are never products that are simply "judged by appearance and price". Instead, they are non-standard industrial products that are evaluated based on their structure, materials, craftsmanship, and quality control.
If the mold venting is not done properly, the yield rate cannot be improved! This article clarifies solutions for trapped gas, charring, and material shortage
When testing many plastic molds, there is always a tricky problem: the edges and corners of the product are charred, the surface is blackened, there are bubbles, or the filling is incomplete. Repeatedly increasing the injection pressure and speeding up the injection rate not only fails to improve the problem, but even makes it worse.
If mold cooling is not done properly, mass production will definitely fail! Let's solve the common problems of mold shrinkage, bubbles, and deformation step by step
In mass production of plastic molds, many quality issues are actually unrelated to mold adjustment, but stem from a core detail: the unreasonable design of the mold cooling system.
Are the molds always deformed and warped after being made? 90% of the warping issues can be rectified in one go like this
In the production of plastic molds and injection molding, the most troublesome common issue is undoubtedly: product warping and deformation.
