what will influnce price for injection mould tooling?
It depends on a lot of factors. A mold can cost from several thousand to hundreds of thousands of dollars, and the most important factors that affect the price of the mold are the complexity of the part that will be produced from the mold, the size and the number of cavities. In addition, we also need to consider more about some other factors such as the injection system (Hot Runner or Cold Runner), geographic location of suppliers, or some other requests...
Hot Runner or Cold Runner .Using Hot Runner or Cold Runner in Injection system will also affect the price of a mold. Obviously we all know that Hot Runner is different from Cold Runner, and the cost is also different.
Surface finish. If the surface finish is not critical then a machined finish may be acceptable — this does not require secondary finishing thus reducing the time and cost to produce the tool. Hand polishing takes time and effort and has to be built into the cost of the tool.
Geographic location of mold suppliers. According to an evaluation, choosing to buy injection tools manufactured in China will help you save cost up to "40% compared with a typical tool price from Europe or the USA". However, you should also consider the expenses of travelling to the factory to ensure tools are built correctly. Of course, there is another choice for that is to choose third party company, which can help you audit the process and inspect tooling.
