Using for attaching the grommets.

ALWA UP GELCOAT is an aluminium filled polyester surface resin with a temperature resistance of 110 °C. Pot life is approx. 20 – 30 min. at room temperature, when using 1 – 2 % hardener (art. no. 3150001). The top layer can be polished to high gloss.

The solvent combination contains methyl methacrylate (MMA) and is used for diluting and cleaning.

ALWA PU foam consists of component A (art. no. 9700005) and component B (art. no. 9701006) and is used, for instance, to produce displacers. The mixing ratio between component A and component B is 1 : 1.2 and the density is approx. 30 kg/m³.

ALWA release wax (art. no. 9516000) is used to release patterns and moulds. ALWA release wax is applied in a thin coat with a brush or a soft sponge. After the solvent has evaporated, a polishable release film is formed.

Release agent H1 (art. no. 9519000) is used to release patterns and moulds. Release agent H1 is applied in a thin coat with a brush or a soft sponge. After the solvent has evaporated, a release film is formed.

The mould construction fleece is particularly well tensile and conformable. It is also ideally suitable for complicated parts and moulds. Since this fleece is produced of 100 % polyester fibres, it can be processed with epoxy and polyester resin without any problem. The resin consumption is approx. 1.5 – 2 kg/m² depending on the application. It is ideal for producing free forms.

ALWA BARRIER COAT is a laminate resin, which is applied to protect the gelcoat for instance with glass fleece (e.g., ALWA MOULD COAT and ALWA UP GELCOAT).

ALWA EPF 10 is a temperature-resistant, steel-filled gelcoat based on epoxy resin. It is used to produce temperature and abrasion resistant surfaces for vacuum, PU foam, thermionic moulds and heating plates, among others.

ALWA EPT 210 is a laminate and backfilling resin. Laminates can be produced with ALWA EPT 210 in order to manufacture glass fibre plastic parts, gauges, templates, moulds and applications with diverse fillers. ALWA EPT 210 is an epoxy resin that has a low viscosity and a light yellow colour. Under exothermic reaction, it cures in connection with the light yellow hardener H 10 at room temperature. The mixture shows a low viscosity and is particularly appropriate for laminating layers of up to 8 mm. For thicker laminates the application of layers must be interrupted several times in order to avoid too high reaction temperatures in the laminate.

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 plasticine is used to repair master patterns, round off sharp edges, seal casting boxes and build a parting plane.

ALWA acryl sealer is used to seal porous surfaces, such as wood, gypsum and rigid foams (not suitable for polystyrene foam). The primer dries in the air and forms a strong film. Apply a thin layer of ALWA acryl sealer evenly with a brush. If 3 % hardener powder is added, the curing process can be reduced to approx. 30 min.

225 gr. spin split glass fibre mat as well as 450 gr. emulsion bound glass fibre mat are offered.

Steel wires are required for the vacuum channels.

Copper pipes are used as heating and cooling coils (very soft and, therefore, easy to bend).

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

ALWA release spray (art. no. 9515000) is used to release patterns and moulds. After the solvent has evaporated, a strong release film is formed. ALWA release spray may not be polished.

ALWA release lacquer (art. no. 9510000) is used to release patterns and moulds. ALWA release lacquer is applied in a thin coat with a brush or a sponge. A thin coat of ALWA release lacquer can also be sprayed on with a conventional spray gun. We recommend to spray on approx. 2 to 3 layers. After approx. 20 min. a strong release film is formed. The drying process can be accelerated by hot air.

Master patterns must be treated with ALWA surface tension remover (art. no. 9500000), so that the ALWA release lacquer does not roll off. ALWA surface tension remover is applied in a thin coat with a brush or a sponge. After approx. 10 min. the solvent is evaporated and ALWA release lacquer can be applied.

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

Moulded-In Inserts are placed over core pins by an operator or a pick-and-place robot prior to the closure of the mould cavity during the plastic injection process. Moulded-In Inserts offer exceptional torque and pull-out resistance due to unrestricted plastic flow around the Insert body, and are often the Insert of choice for thermosets and engineered plastics with a high percentage of filler. The minor thread diameter tolerance is controlled to ensure positive positioning and perpendicularity of the Insert on the core pin during the moulding process. Series 63 is symmetrical eliminating orientation and Series 65 is the same body style in a blind ended version. SPIROL's Moulded-In Inserts are made from 2024 aluminium, a light-weight, lead-free grade. SPIROL’s Series 63 and Series 65 Moulded-In Aluminium Inserts are available in thread sizes ranging from M4 (8-32) up to M8 (5/16-18).

Injection moulding of rubber and plastic. Plastic products for the vehicle manufacturing industry.

We manufacture rough or fully machined continuous casting moulds in pure copper

A calculated evaluation of the type of steel is necessary, in accordance to the compound that will be used on the mould, so as to compensate the effects that they can have, and also to permit more longevity of the mould itself.

Chrome Plating Shiny / Opaque surface finish An electroplating process whereby chrome is deposited “on and below” the surface of the mould. Different types of chroming procedures may take place, depending on type of compound to be used, and aspect/use of the moulded part. Facilitated compound flow Easier demoulding Reduced frequent mould cleaning Longer mould life
