As an outstanding car parts supplier in Germany, the client has cooperated with several world-famous automobile manufacturers for years. The client found RPWORLD, asking for 30-50 sets of newly-designed water tank of advanced automobile to test the performance. And applying the real materials was required, which ensures the design and chosen material were fully under verification. To complete the performance test and put into mass production, the client expected to receive the prototypes in the shortest time.
There was a hollow thin tube with length 250 mm and diameter 3 mm. The complex geometry structure made the production a challenging work.
The real materials should be used (PE and PC were appointed). Real materials cannot be applied in all processes. Only the engineering team with skill and experience who were aware of pros and cons of each process will enable the production.
The leading-time was tight. Though it was a program with difficulties, we were asked to deliver within 30 days, for they wanted to accelerate the speed to market after testing.

Experienced engineers went a thorough discussion about the most suitable process for products, and they all agreed that Urethane Casting process would be a prior choice for 20 sets of housing. What’s more, 50% cost will be reduced after adjustment of products for urethane casting manufacturing compared with previous process. As for material, ABS type PU was recommended, which is a perfect and most commonly used material for urethane casting. At the same time, it is an anti-corrosion material with a certain hardness, and widely used under circumstance of room temperature.


√ By offering the most flawless industry solutions, RPWORLD streamlines development process. In addition, RPWORLD regards customers as product development partners and takes that belief through each step of the production life circle. What we used to produce the prototypes reduced production time by 50%, and the cost was only 50% of mass production. We meet the needs of the customer perfectly.


We have to say that the cooperation is just beyond my expectation. Let aside the high quality and early lead time, the production cost was reduced greatly, which really surprises us a lot. RPWORLD just fulfils my imagination of a perfect team. Currently, the same process was used in other similar projects. I really appreciate what you have done, and now please work on my next project!
