In the process of using injection molding machines to process plastic products, it is inevitable that some unexpected plastic injection molding parts defects phenomena will damage the quality of the products.

What is plastic injection molding parts Dull Areas Near Sprue?Apparently, there is a discernible ring around the sprue - if a central gate is used, it is a central circle, and if a side gate is used, it is a concentric circle. This is because the ring size is small and looks like a halo. This occurs mainly when processing highly viscous (low flow) materials such as PC, PMMA and ABS.

1. Whether there is looseness when the injection Mold spare parts guide rod and bushing are matched with the template (large fit tolerance)2. Whether the injection Mold spare parts guide rod and bushing are strained and rustedThe guide rod mainly plays a guiding role in the mold to ensure that the molding surfaces of the core and the cavity do not touch each other under any circumstances, and the guide rod cannot be used as a force-bearing part or a positioning part.

We all know that OEM high precision plastic injection mold can only be transferred to mass production after being verified as ok, so what are the requirements for mold core runners during mold acceptance?

Recently, many friends have emailed or called to learn about PFA teflon plastic injection mold, that is, Teflon injection molding customization

Injection Mold spare parts Ejector pin selection principle(1) Use a Ejector pin with a larger diameter. That is, when there is enough ejection position, the ejector pin with larger diameter and size should be selected.(2) The specifications of the Ejector pin should be selected as little as possible. When choosing a Ejector pin, the size of the Ejector pin should be adjusted to minimize the size specifications, and at the same time try to choose the preferred size series.(3) The selected Eject…

With the rapid development of new energy vehicles in recent years, China's local wiring harness connector mold parts suppliers have taken the lead

​At present, in the mainstream technology of injection molds, mold runners are divided into hot runners and cold runners, and cold runners are divided into high precision plastic injection mold runner balance and high precision plastic injection mold runner unbalanced types. Today, the advantages and disadvantages of balanced cold runners in injection molds are discussed in detail.

OEM & ODM high precision plastic injection mold molding, the number of each injection molding is the number of cavities, and the usual number of cavities is from 1 to 192.

High precision plastic injection mold design refers to the personnel engaged in the digital design of enterprise molds, including cavity molds and cold stamping molds. On the basis of traditional mold design, digital design tools are fully applied to improve mold design quality and shorten mold design cycles.

Do you know some of the details of the connector mold design? Connectors should not be unfamiliar to engineers. One of the very common components is the bridge between devices.

​The definition of Medical plastic injection mold core pulling mould is as follows: Any features that will interfere with the direction of the product and the direction of leaving the mold cannot be demolded. In places like this, it is necessary to remove the interfering steel material after the mold is opened (some Time is before the mold is opened) to remove it first to ensure that the product is smoothly removed from the mold. Therefore, the mechanism that realizes such a function is calle…
