The original model for vacuum casting is generally created using the stereolithography method. From this model, a primary mold of silicone is created and filled in the vacuum chamber with liquid polyurethane casting resin (PUR). The vacuum prevents bubbles and shrink holes even in complex molded parts. After hardening, the service of the casting is finished. Given the numerous available polyurethanes and ureols (PU hard foam), many conventional production plastics (injection molding) can be simulated.
Whether rubber-soft, last, semi-rigid or ABS rigid, there are vacuum casting resins for a very wide range of material requirements and priorities. Two component parts (hard/soft) or inserts are also possible. The dimensional precision of molded parts in vacuum casting is �± 0.1 mm or 0.2%. In vacuum casting, the maximum yield from one silicone mold is approximately 20 molded parts. There are no demolding chamfers and added material to compensate for shrinkage in vacuum casting.

The Incinerated scrap or E46, is the by-product derived from the reprocessing of incinerated domestic waste. After the combustion process, the furnace output (IBA Incinerator bottom ash) is firstly washed, magnetically separated and screened to separate any no ferrous material. At a visual inspection, the material is fragmentized, with iron and steel parts, resulting partly cut or in shredded form. The stock appears heterogeneous and contains all kind of cut or dismantled steel parts such as sheets, bars, frames, wires, bolts and other iron/steel household residues. The incinerated scrap is eventually oxidized, due to the thermal and cooling treatments, that the material has been submitted to. The burnt scrap also contains minor slag parts, ash and iron oxide, due to the recovery process. Such components are inherent and adhere to the scrap surface. The total impurities, can be sorted, but not fully removed. The consignment does not contain any type of arms, ammunition, mines, shells, cartridges, radioactive contaminated, or any other explosive material in any form either used or otherwise. The collected stock, is stored in open air, on cemented flooring. It can be loaded loose in 20â?? heavy duty container. Please feel free to contact us for further details.

Vacuum casting technology offers a wide variety of materials to facilitate the creation of cast urethane parts, typically for functional test, pre-production evaluation and low volume production. Cast auto urethane parts are quick and inexpensive without the need to invest any metal tooling when quantities are only dozens of short runs, and can be delivered within weeks in most instances. Standard lead time Up to 10 copies within 15 working days Standard accuracy ±0.3% (with lower limit on ±0.3 mm on dimensions smaller than 100 mm) Minimum wall thickness To ensure that the mold is filled properly, a wall thickness of at least 0.75 mm is necessary. For best results, we recommend a wall thickness of at least 1.5 mm Maximum part dimensions The size of the mold is limited by the dimensions of the vacuum chamber (1900 x 900 x 750 mm) and by the volume of the product (maximum volume: 10 liters) Typical quantities Up to 25 copies per mold (depending on the mold's complexity and the casting materials) Surface structure High-quality surface finish comparable to injection molding. Advantages of Silicone Auto parts Vacuum Casting : Great for low volumes Self-coloured parts Low upfront investment Production like parts Massive range of materials Rubber like parts and over molds
