injection mold costs in China, is it cheap or expensive?

Our mold costs start with an amount of approximately 1000 USD / euros for small molds , creating small parts with dimensions such as 50*20*10 Mm..

Injection molding China by Triple-c is therefore only feasible ( due to these necessary start-up costs ) for producing series starting from approx. 1000 products.

In order to make a good estimation of the mold costs, it is important that the design of the desired product is finished and according our general design rules, and that the expected production volume per year is known. Additional information as part material and quality, product life time will be used to fine tune the mold costs..

The shape (and therefore price) of the mold is in fact determined by

The design of the product: the more complex the design- structure of the product, the more mold parts are necessary to shape it.
The expected production or manufacturing volume: the greater the expected volume, the more sustainable the mold should be

The 2 main aspects that determine the cost price of a mold are listed below.

The shape and size of the product determines mold cost in China

Product size: the larger the product, the larger the mold.
In the simplest scenario, the mold has one split line and therefore consists of two halves. However, many products are provided with all kinds of details and require a more complicated mold construction, such as sliders.
The requirements that are set on the product surface.

The number of products that you would like to make with one mold

In a situation of annual deliveries of up to 75,000 units, a single mold is usually used. That means: a mold with one product cavity. With a larger annual requirement, the number of cavities (cavities) can rise to more than 90. This depends on your machine and of course part size. With extreme large injection molded prats we stick to one cavity.
With large annual order quantities, it is important that the mold can be maintained in a simple way. with this purpose in mind the construction of the mold needs to be optimized at this point.

High pressure (up to 2,500 bar)

This requires a very stable mold construction. In practice, this means that most molds are made of steel.
Every detail on the steel mold cavity is visible on the end product.for this reason a scratch or a small damage will also be visible on the product. That is why the steel parts in the cavity of the mold are often extra hardened and made very wear-resistant.
all small openings in the mold cavity that is larger than a fraction of a millimeter (0.03 mm.) Is visible on the product. The mold parts must therefore be processed very accurately.
