Resin casting - Import export

The Systems comprise the entire casting process: Preparation of the material components resin and hardener (conveying, homogenization, degassing), production of the reactive mix and casting of the parts under vacuum/atmosphere. Any resin system can be processed, also with strongly disproportional mixing ratios.

Together with the Fachhochschule Münster – University of Applied Sciences we are working on ALWA PERM (patent No. 2583995). This is a metal-filled casting resin for producing a porous, resin-bound mould. These materials are applicable in the areas of thermoforming, the ceramic industry, intake moulds and devices, pneumatic cushioning, the filter industry, etc. ALWA PERM allows a castable production of porous metallic materials with a binder for the first time. The system offers a highly accurate mould surface reproduction. The profile characteristics goes far beyond the current state of the art. NO MORE DRILLING OF VACUUM HOLES! NO DAMAGE OF THE MOULD SURFACE DUE TO DRILLING HOLES

ALWA MOULD SLV is a universal two-component fast casting PU resin for mould making. It is used for the production of milling devices, negatives, product holders, foundry moulds, mould plates, copy moulds, core boxes, pattern plates, casting moulds, prototype parts, supporting moulds and synthetic cast. It consists of a beige-brown low viscosity resin component A (polyol mixture) and a red-brown, low viscosity hardener (component B) based on isocyanate (Methylendi(phenylisocyanat)e = MDI). Two types are available with different pot life: *ALWA MOULD SLV 3 ~ 3 min. pot life *ALWA MOULD SLV 9 ~ 9 min. pot life

ALWA MOULD P is a cold curing casting resin for the production of porous moulds, slabs and blocks for the ceramic industry. It is a porous and high-strength plastic, which is well-suited for high pressure casting applications. ALWA MOULD P can be used in various areas of the tableware and sanitary ceramics, technical ceramics, plastic mould procedure as well as various filtration processes. The high stability and defined porosity of the material allows highly accurate mould surface reproductions. With ALWA MOULD P various geometric moulds for filtration processes of suspensions can be produced. ALWA MOULD P can be used for ceramic slip pressure casting procedures. In this procedure, water is removed by a filtration process of a clay suspension (slip), so that an increasing clay layer is built on the mould wall over time. The moulds, slabs and blocks of ALWA MOULD P are easily machinable (e.g., drilling, milling).

Aluminium perforated sheets are used in order to reinforce the casting resin moulds.

ALWA repair filler (art. no. 5100001) is used in order to repair casting resin moulds. The filler is mixed with 1 – 3 % hardener powder.

ALWA HT RESIN is a resin-based on isocyanate and epoxy (EP), which reacts after adding a catalyst. ALWA HT RESIN offers a range of possibilities for producers of fibre-reinforced materials (e.g., glass fibre, kevlar and carbon), semi-finished and finished goods. The system is also suitable for prepreg and reaction compounds. ALWA HT RESIN is particularly interesting for the aerospace and aircraft industry as well for the rail transport, automotive and electronics industry. The application area of epic resins are electro casting resins, lamination and injection technology (RTM procedure), vacuum infusion, casting and ramming compounds, impregnation resin, casting and injection moulding process as well as prepreg technologies, among others. ALWA HT RESIN is offered in two versions. *ALWA HT RESIN M100 with approx. 50 mPa s *ALWA HT RESIN M2200 with approx. 2200 mPa s The resins can be mixed with one another which enables a flexible adjustment of the viscosity.

The Systems comprise the entire casting process: Preparation of the material components resin and hardener (conveying, formulation, homogenization, degassing), production of the reactive mix and casting of the parts under vacuum/atmosphere. Any resin system can be processed, including fillers, and also with strongly disproportional mixing ratios.

The casting lines comprise formulation, preparation, mixing, metering and casting of the parts. Also included is a pre-heating zone for the parts resp. molds prior to the casting devices as well as gelling and curing ovens systems. Fully automatic flow of the parts/workpieces through the entire process, from pre-heating to curing.

In-line conveyor ovens: Pallets pass through the oven one after the other. Automatic batch ovens: The oven is charged with pallets while kept at a temperature below the gelation temperature. After the last pallet has been loaded, the temperature cycle is started for the whole lot. The oven is emptied in a rapid process after the complete temperature profile has been run through. Stack ovens: Pallets are loaded into the oven. When each row has been filled, all the rows of pallets are lifted up by one level. When one row of pallets has reached the uppermost position of a temperature range, it is pushed into the next temperature zone and from here is lowered down in fixed time cycles and unloaded. Serpentine conveyor ovens: Pallets are loaded into the oven in fixed time cycles and pass through the individual temperature zones.

You manufacture sensitive electronic products, such as power semiconductors, diodes, diesel injectors and components for medical equipment. For casting purposes, you need systems that guarantee perfection and absolute freedom from voids with minimum casting quantities. Our Micro Casting Systems: Accuracy: Absolutely error-free casting of the smallest quantities; casting quality tolerance less than 0.01 g. Flexibility: Suitable for highly filled, abrasive casting resins under vacuum or atmosphere. Control: Patented dosing control unit for plant and process monitoring; glass cylinder design also allows direct observation of the preparation process.Compatibility: Modular design; cell construction makes it ideal for integration into existing production lines.
