Mange sprøjtestøbefabrikker vil støde på lignende problemer. Der er ingen problemer med produktkvaliteten, men produktets glans er ikke op til standarden, hvilket i sidste ende fører til afvisning af de sprøjtestøbte dele. Ud over problemerne med selve plastikken, der er også problemer som sprøjteskimmel, produktion, Hvordan man opnår højere produktydelsestolerance i sprøjtestøbebearbejdning, etc
1. I sprøjtestøbning produktionsprocessen
Der er flere muligheder at prøve, som kan ændres ved at justere formtemperaturen, foder / hold pressure, fill rate, and material temperature. I de fleste tilfælde, these adjustments will not have a significant impact and will reduce the process window of the whole production, thus increasing the possibility of other problems. Derfor, it is best to find the most robust process for the part and maintain the surface finish of the cavity mold.
2. In terms of injection mold
When dealing with the problem of gloss, do not change the surface finish of die steel at the first step. Tværtimod, it is necessary to adjust the process parameters to change the glossiness of the product. Lower mold temperature, colder melt, lower feeding / holding pressure and lower filling speed may make your plastic parts glossier. The reason for this is that the plastic is not copied into the micro details of the surface finish of the die steel due to the lower die temperature and the lower pressure applied.
Tværtimod, the higher the injection mold and melt temperature, the higher the feeding / holding pressure, and the faster the filling speed, the darker the luster of your parts will be. The influence of melt temperature is not as great as the filling speed, because the influence of filling speed and the resulting shear force on material viscosity is much greater.
På den anden side, if the surface gloss of the product is too high, it can be considered to reduce the surface gloss of the die steel surface or sandblasting in the mold cavity. Both methods create small pits in the steel, increasing the surface area, which allows the injection molding to absorb more light and thus appear to darken your parts.
3. In the design of injection molding products
Another major cause of gloss problem is the design of the product, especially the position where the wall thickness of the product changes. When the wall thickness changes, it is difficult to maintain the uniform gloss of the parts. Due to the difference of flow patterns, the thinner wall section will not be under too much plastic material pressure, and the result is that the glossiness of the area will be higher.
Inadequate exhaust will also produce inconsistent surface gloss. Depending on the material and process, insufficient exhaust will cause dark spots and bright spots.
The above three points are important factors affecting the glossiness of injection molding products. As long as the injection molding manufacturers consider these problems in place before producing products, they can avoid the problem of glossiness of injection molded products.
