apra-plast Kunststoffgehäuse-Systeme GmbH
About us
apra-plast Kunststoffgehäuse-Systeme GmbH develops and manufactures plastic parts and housings with optimal functionality according to customer requirements - from prototypes through small series to series production with several thousand pieces. Technically mature, visually appealing and with an excellent price-performance ratio - even without tool costs.
Do you have individual requirements for your housing? Do you need an individual design, have special technical requirements and need a powerful partner? Then you have come to the right place at apra. The specialists take their time and advise you from A to Z.
What distinguishes apra? apra not only has the right production technology for every quantity, but also realizes unusual housing solutions in shape and color according to your individual requirements. Unmistakable plastic housings for mechanical engineering, medical technology or control technology are created from the multitude of color options in the raw material and the possibility of individual surface refinement through painting, printing, etc.
Products & services
For prototypes, pilot and small series... Vacuum casting SYNPRO
The SYNPRO Vacuum casting technology is a particularly economical process for the production of prototypes and pre-series or small series. With SYNPRO, we realize even minimum batch sizes without high tooling costs, in the desired design and “just in time”. Our special SYNPRO vacuum casting technology is particularly suitable for the production of plastic parts with special requirements and for the recasting of components. Different materials that can be combined with each other provide additional design flexibility. We develop 3D design proposals or 3D constructions for you according to your ideas and produce an individual master model. For this, we use our modern 3D printing processes. The casting mold is created by pouring silicone onto the finished master cast. The mold cavity is then filled with casting resin under vacuum. The materials that are used have a wide variety of properties such as shore hardness, temperature resistance, impact resistance, fire performance and a wide range of approvals (FDA, etc.). There are almost unlimited options for the colouring of all materials including the possibility of transparent variants. All sprues, separation points and material residues are carefully removed during reworking. Subsequent holes and threads can be inserted without any problems. Highlights particularly economical process for prototypes, pilot and small series customized design without high tooling costs “just in time” combination of different materials PU-based 2-component casting resin different colours, transparent variants available subsequent holes and threads can be inserted without any problems
Prototypes 3D-printing
You give us an idea of your project (sketch, drawing, model) and we can offer you the following apra-plast services: Fast, flexible and cost-effective – ideal for prototypes! We can produce a 3D prototype with high stability and resolution at the development stage of your product. This can also be used as an individual master model for vacuum casting. All we need are your IGES or STEP files. Highlights 3D prototypes high stability can be used for vacuum casting possible size: 298 x 210 x 200 mm accuracy: up to 0.05 mm
Milling/bending technology for small and medium quantities – without tooling costs
Our milling/bending technology makes it possible to implement individual designs cost-effectively. With this high-precision and powerful process, we can also manufacture smaller quantities flexibly and quickly – without any additional tooling costs. Thanks to the wide range of materials, colors, and accessories, we can produce unique housings and plastic parts that are perfectly tailored to our customers' requirements.
