Die casting moulds - Import export

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

The patented casting resin system ALWA MOULD D consists of two resin components and an aluminium filler. The fast curing of the material allows to produce your own technologically highest quality moulds in just a few hours. As our material is very good castable, compact moulds of any desired volume can be made from our product, such as acrylic baths, boats, etc. (<1 kg – 2500 kg). In comparison to other materials (e.g., glass fibre reinforced plastic), the system is more temperature-resistant, allows castings without air bubbles and does not have to be post-cured. Furthermore, the finished mould is easy machinable (e.g., drilling, milling, grinding, planning, sawing, turning, etc.). ALWA MOULD D moulds can be modified with repair filler, so that a fresh view can be created at an early stage of a new design process and prototypes can be examined at short notice.

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

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

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).

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.

FLUX air-operated diaphragm pumps are self-priming and protected against dry running. The pumps are distinguished for their versatility and can be used for virtually all types of media. Available in heavy duty (RFM) or injection-moulded/cast (FDM) version for a huge diversity of applications they are designed for high pressures of up to 8 bars and in addition to other properties they are outstanding for their ease of handling. The 100 % start-up guarantee in every shut-down position guarantees reliability and safe operation. The flow is infinitely variable via the air pressure. In addition the flow rate is easy to calculate. As a result of the integrated silencer the compressed air-operated diaphragm pumps are low noise. In addition the pumps are low-maintenance, in particular if used for pure media.

Parting agent for casting, injection moulding, blow moulding and extrusion processes of plastics and elastomers Prevents sticking, for example of excess adhesive and sealant Eliminates creaking and squeaking noises when surfaces made of plastics, elastomers and metals rub on each other For easy fitting of plastic and rubber profiles, e.g. in door and window construction Lubricant for cutting edges of paper, cardboard, veneer or textile machines, etc. Advantages and benefits NSF H1 registered Highly effective due to outstanding surface wetting and formation of separating film with antistatic properties Broad range of uses for long-term lubrication, protection, care and impregnation of material surfaces made of metal, plastic and rubber Minimal consumption through formation of extremely thin films Resistant to water and weathering Long spray tube for precision application MOSH/MOAH-free

EPS MEANS OPTING FOR MAXIMUM FREEDOM. Technical molded parts made of expanded polystyrene (EPS) are the material of choice when it comes to good moldability, light weight, and outstanding insulation. EPS is ideal for the lost foam casting process. This involves embedding an EPS foam model of the desired component within a casting chamber in molding sand and dissolving it by pouring in molten metal. Compared to other processes, this affords greater design freedom when creating the cast parts, because neither built-in parts nor connections are necessary. As such, even complex cast components can be produced easily and particularly inexpensively. EPS also serves the construction industry well: Due to their very low thermal conductivity, technical molded parts are used as insulation elements and panels for underfloor heating systems. They can also be used as formwork elements. Whether for individual geometries or technically demanding structures, EPS makes it possible.
