Mould cores - Import export

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

We carry a range of standard moulded plastic cores with special bores resp. threads, which can be produced in large numbers.. If your application allows we recommend you to choose one of our standard cores. It is reasonable and advantageous concerning the delivery time and costs, for smaller quantities too.

Should you have not been able to find the suitable lath brush for your application although our standard range is most versatile, we trust that our special types might come up perfectly to your requirement. They also offer best quality to meet your most particular wishes. You can choose for instance between frame shape, angled or arched shape; special fixing devices such as round drill holes or slots; threaded, grooved or clamped holding devices. In case of large-scale requirement we also provide especially moulded plastic or metal cores made either by injection moulding or diecasting. Please see the index card "brush assembly" for the core material. Furthermore we have wood, steel, stainless steel, light or heavy metal in our assortment.

Kullen-Koti disc brushes can be supplied with various fill configurations. For example with compressed face, with narrow or large fill collars, with fill array in particular forms, either with normal vertical bristle bundles or with inclined bundles to all directions. We supply core material according to your application purpose, for example cores made of plastic qualities PP, PA, PE, POM or PVC as well as of wood or different steel and metal types. On request of big quantities it is worth to use moulded plastic cores. Almost all fill material qualities can be used, e.g. natural hairs and bristles, plant fibres, synthetic filaments and wires. We can supply disc brushes matched to your requirements with bore hole, thread or shaft for fitting in the machines.

Foundry grade bentonite is used in foundry industry as a mineral binder in the compositions of molding and core mixtures ("green sand" technology)

Visionary concepts come true with upcrete® modular moulds – even complex concrete structures can be produced with smooth surfaces on all sides. The room module mould with “flying” shrinking core was the fi rst room cell mould developed in Hockenheim and was used for a modular housing project for a Peruvian customer. This mould variant is based on the upcrete® technology, in which self-compacting concrete is pumped from below into a closed mould. This process allows the concrete to optimally distribute within the mould and yields smooth surfaces on all sides, as well as precise edges and recesses. Another advantage is that the structure can be produced in its fi nal installation position, which means that subsequent turning is no longer required.
