01 / OUR EXPERTISE
Equipment and materials
for industry.
Our solutions support foundry and metallurgy operations, the production of forgings, extrusion and wider industrial processing. Explore equipment, materials and process technologies for each stage of production.
Foundry & casting
Induction melting furnaces, moulding lines, core production and sand systems, including no-bake moulding and investment casting.
Raw materials
Recarburisers, graphite, inoculants, foundry binders, refractory coatings, crucibles and industrial ceramics, alongside casting waxes and release agents for rubber and composite processing.
Air & filtration
Air pollution control through industrial fans, filtration and dust and fume extraction — extracting airborne contaminants from foundry, metalworking and other industrial processes.
Material process & handling
Material processing and handling: vibratory feeding, screening, shakeout, crushing, heating, drying and cooling, plus very high temperature ID tags and metal briquetting.
Surface & finishing
Mechanical surface preparation, from shot blasting and shot peening to fettling and grinding, deburring and polishing, with abrasives and equipment for finishing operations.
Quality control
Sand and laboratory testing equipment for foundry quality control.
Heat treatment furnaces & auxiliary equipment
Heat treatment furnaces and auxiliary equipment, with refractory materials and furnace linings for demanding thermal processes.
Recycling, process sorting & transport
Recycling, process sorting and material transport solutions. Discuss material recovery, process efficiency and your carbon footprint goals with our team.

CHEM-TREND / RUBBER & COMPOSITE PROCESSING
Mould release agents for rubber and composite processing
Release agents for rubber and composite processing, with conventional and semi-permanent options selected to suit the material, mould and production process. Rubber applications include injection, compression and transfer moulding of seals, gaskets and rubber-to-metal components. Water-based and solvent-based options are available.
Easier release
Help demould rubber and composite parts more consistently and support surface finish and part quality.
Cleaner moulds
Help reduce mould fouling and residue build-up, extending intervals between cleanings.
More productive cycles
Semi-permanent systems can reduce reapplication frequency and cleaning downtime.
Air pollution control & industrial fans
From identifying the problem to designing a solution and installing equipment: welding fumes, oil mist, abrasive dust, furnace dedusting, sand systems, fettling shops, asphalt and wood industries.
