China Custom Injection Molding Injection Molded Part

At Davantech we are injection molding since 2010. We are a mold maker and manufacturer of plastic products in China. It is still an obvious choice to have your molds made in China. The manufacturing supply is very efficient and as a result we can offer molds much cheaper.

This is a benefit for you.

We use steel molds to do the injection molding of plastic products. A mold is a one-time investment. It allows you to produce simple as well as complex plastic parts in an fast and economic way.

The life time of a steel mold can vary from 100 000 cycles to 300 000 cycles for a standard mold. However it can go up to more than 1000 000 cycles for expensive molds. This lifetime is depending the type of steel, hardened or not, and the type of plastic to be used in the mold. Glas fiber filled plastics will reduce the lifetime of a mold, for example.

Our mold division needs an average production time of 35 working days to finish a mold. We do the mold test once the mold production is finished. It is possible dough that the mold needs adjustment. We will apply the surface texture or polishing after the plastic parts are accepted by our Quality department. We ship final samples to the customer for acceptance.

The production of series starts once the samples are accepted.

We count about 20 days for the total process. The production of each order is scheduled. Our procurement department will buy raw material in case there is no stock. One mold we can do 1500 to 2000 cycles per day. Parts are checked after injection molding. We will remove burrs and pack the goods. Ready for shipping

Injection molding of plastic parts is a very efficient production method. Especially when we can produce large quantities. The mold below has 12 cavities. This means we can produce 12 parts for each mold cycle. The result is a far cheaper unit cost per part. The mold, however, is more expensive. Nevertheless you will win the extra cost back in the total production cost of the plastic parts.

Injection molding of plastic is an industrial process. Molten plastic is injected with high pressure into a mold. The mold is closed with a big force and remains closed during a certain time. The cycle time is depending on a number of factors such as plastic volume, wall thickness and type of plastic. A good design will reduce the cycle time.

There are 3 parameters to setup an injection molding machine :

Each type as well as each different product needs different parameters. In addition the shrinkage of each plastic type is different. The cavities in the mold are larger than the final part. The reason is this shrinkage. A part will shrink once it is ejected from the mold. A part made of POM can shrink up to 20%.

Products with a too big wall thickness can shrink even days later. Again, it is important to design a plastic part in a correct way.

Raw material used for injection molding depends on the use of the final product and the desired properties. There is a price difference between different types of plastic.

For cheaper plastic products where the finish and looks are less important we mostly use PP (Polypropylene). This is a strong material with good chemical resistance. It is used for outdoor furniture as well as toys. However PP is not suitable for gluing and printing. We need to do a surface treatment first.

Housings of electronic devices will mostly be made of ABS of PC-ABS. This because of its robuste properties, temperature resistance and surface finish. PC or PC-ABS is more rigid and impact resistant.

Strong (tough) parts and moving parts will be made of PA66 and POM. (these materials are also suitable for machining

In our injection molding department we have 9 injection machines up to 560 Tons. For smaller parts and over-molding we use vertical injection machines from 25 to 45 Tons.

Our factory is well organized and flexible. We are ISO9001:2015 certified as well as RoHS and REACH. Other certification and analysis of materials are possible via SGS.
