Processes
Splitting / shaving is the mechanised process of reducing large blocks of material into thinner sheets. EVA Industries manufactures polyethylene and EVA foam sheeting in a wide range of thicknesses and densities, as required by our customers.
EVA Industries makes use of specialised splitting machines. These machines are set either manually or electronically by skilled operators. The foam blocks are loaded into the splitting machine by the machine operator. The block is then sliced by the machine to the required thickness. The machine controls the speed at which the block is sliced, depending on the density of each block and the required thickness of the final product. The sliced blocks become sheets during this process.
The machine operator is supported by a table hand who receives the sliced sheet upon exit from the splitting machine and then packs the sheets onto a pallet for further quality inspection, processing, or dispatch.
Examples of uses for split sheets:

Split sheets can be used for insulation, gasketing, footwear components, camping mats and yoga mats, to name but a few.
Injection moulding is the process in which a thermoplastic polymer is heated above its melting point and then mechanically injected or pressed into a mould.
EVA Industries manufactures injection moulded PVC (Polyvinyl Chloride) or TPR (Thermoplastic Rubber) products from various moulds according to customer specifications. EVA is a large user of in-house injection moulded products but also services a broader customer base with its injection moulding capabilities.
EVA has an injection moulding department compromising single-colour vertical and two-colour rotary injection moulding machines.
Examples of injection-moulded PVC products include:
PVC vamps for beach thongs
PVC vamps in the injection moulding machine
PVC/TPR outer soles for shoes

CNC routing is a highly specialised process of milling a material into various forms or shapes. The CNC router uses CNC (Computer Numeric Control) programming to instruct the machining head to follow a set programme. The CNC router has multiple machining heads, with each head having a unique bit application. The CNC router can change bits whilst running a single programme. This ability results in efficient production with consistent results.
EVA Industries uses the CNC cutter to cut through EVA manufactured foam materials to create bespoke CNC foam products, as per customer specifications. These products range from gaskets to dunnage (inserts). The applications are varied across automotive, agricultural, building, industrial, recreational and footwear sectors. Customers provide the CAD (Computer Aided Design) designs and specifications.
Our factory provides external CNC cutting services to a broader base of customers.
The CNC cutter affords EVA Industries the opportunity to repurpose blocks and sheet material through value-add processing that meets customer specifications. As part of our company’s commitment to reducing its carbon footprint, the CNC cutter can therefore add value to the repurposing initiative. EVA Industries makes use of its own manufactured materials wherever possible.
Examples of CNC routed EVA products:
- Value-add branding on EVA blocks and sheeting for customers
- Value-add roughening on footwear-related materials
- Any design or application, where applicable, according to client specifications

Die cutting is the process of stamping out shapes of material from blocks and / or sheets. The process itself involves specialised hydraulically operated machinery combined with skilled operators and unique dies (or knives), which are pressed down in a quick motion under pressure. This results in a stamped cut into the material. The shape of the knife becomes the product, and the product is removed manually from the material, resulting in both a fit-for-purpose product and a skeleton.
EVA Industries die cuts foam sheets into specific shapes using specialised dies. For example, we use a different size die for each size of beach thong that we make. We can manufacture EVA/EPDM foam products according to client specifications using custom dies. EVA makes use of its own materials wherever possible.
Examples of die cut EVA products:
- Soles for flip flops
- Any design, where applicable, according to client specifications

Gasketing is the process of cutting, stamping or manufacturing gaskets from materials ranging from foam, rubber, silicone, graphite, steel and cork, to name but a few.
EVA Industries can offer clients services that include splitting, oscillating knife and / or die cutting of gaskets. The gaskets are manufactured according to client specifications using customised dies or software. EVA can provide the full service from design concept through to manufacturing the final product and makes use of its own equipment, design software and materials wherever possible.
