Die casting moulds - Import export

PA6 (polyamide 6 or nylon 6) is a common engineering plastic that has many advantages: 1, high mechanical strength: PA6 has a high tensile and compressive strength, good toughness. 2. Good wear resistance: Its surface is smooth, the friction coefficient is small, and the wear resistance is excellent. 3. Self-lubricity: When the friction effect is not too high, PA6 can be used without lubricant. 4. Corrosion resistance: PA6 has a good tolerance to alkali and most salts, and can resist the erosion of gasoline, oil, fat, alcohol, etc. 5, excellent electrical performance: PA6 has good electrical insulation, even in high humidity environment can maintain good electrical insulation performance. 6, easy to process: PA6 molding processability is excellent, can be injection molding, blow molding, casting, spraying and so on.These characteristics make PA6 widely used in automotive, electronic and electrical, mechanical equipment and other fields.

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.

Silicone rubber ALWA SIL SH 22 and SH 33 are silicone impression materials. These materials have extremely high mechanical values. In addition, they are very fast to handle and very easy to handle as well. The two-component silicone rubbers cure at room temperature. After mixing the two components, a low viscosity liquid develops, which crosslinks to a resistant and rubber elastic material. During the crosslinking, no exothermic heat is developed. When 1 – 3 % thixotropic agent is added per component, a spreadable mixture is obtained. Area of application: *Flexible casting moulds *Copy moulds *Moulds with undercuts *Polyurethane casting moulds *Concrete casting moulds

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.

Special machines for the automotive and supplier industry Machine system for low pressure molding - electronics casting The BASEline series combines a compact design and convenient operation and can be used optimally for the majority of low pressure molding projects. Various mechanical components can be put together depending on requirements. The adapted melting device with double-acting piston pump, 4l tank volume and a melting capacity of approx. 1kg/h enables optimal processing of small to medium shot weights and/or quantities. The available clamping force of 9/12kN is suitable for casting surfaces up to approx. 3,000mm². By using the Siemens S7-1200 control with touch panel, the series offers the same ease of use as the larger series.
