First, the surface finish does not exist. Secondly, due to material and process limitations, structural strength usually does not exist. Finally, if your product requires regulatory approval for sale in Europe-that is, you need the CE mark-plastic parts must have flame retardant built-in, which is difficult to find in RP parts. The surface finish and structural strength of urethane castings are closer, but the cost per piece is still too high. This makes forming and forming a viable process.
What are the options for injection molding?
By far Plastic Injection Parts is the most practical way to make small and medium-sized plastic parts. Once the mold is purchased, the cost may reach a few cents per part, and in mass production in 2000, the cost per part may be less than $ 1. The problem is that you have to invest in molds. There are really only two options.
Use short cycle, small batch service, prototype-level molds, suitable for using a smaller number of parts over the life of the mold. The cost of the mold will be much lower than the traditional high-volume mold. Parts costs will be significantly higher than traditional processes.
Hire an injection molding supplier for 3 months to produce ready molds, each mold can hold up to 100,000-500,000 parts. The mold will cost more.
Should my parts be made in China?
Generally speaking, if made in China, the cost of China Mechanical Parts is lower than that made in the United States. Manufacturing your plastic parts in the United States has clear advantages between R & D and manufacturing. It is much easier to keep your engineering team there for a few weeks to adjust all the molds so that everything is placed correctly.
