Plastic parts that have not demoldable undercuts can not be realized with commen mold-technology. The lost-core-application enables us not only to solve this problem in an efficient and very precise way ensuring a high quality. Using this production method, hollow plastic parts can be produced in one shot. Especially when you need a high-class surface and a very precise inner part-geometrie, the lost-core-application is the best solution. We can also sample and produce this kind of molds in house.
