Specifications

WPC EXTRUSION
Wood-polymer-composites are a mixture of thermoplastic synthetic materials and renewable natural fibres to reinforce the material. As a PIONEER in the extrusion of these composite materials, SPG holds a leading technical position.
Based on many years of experience and in collaboration with customers on development, SPG is your perfect partner for WPC extrusion. SPG provides its customers with highly attractive offers regarding the design and manufacture of profile dies for WPC applications based on the development of completely new WPC formulations.
WPC is interesting for many applications due to its excellent price/performance ratio-preferably for outdoors, for the furniture industry and technical products (patio decking, window sills, cable ducts, etc.)

  • Adapted " exflex" tooling systems for WPC profile extrusion.
  • Processing of PVC, PP, PS,ABS with a wide variety of fiber composites in special mixing ratios
  • Custom-designed complete offers for WPC extrusion
  • Resource-saving and highly efficient " green" WPC extrusion
WPC applications 
The principle of sustainability has always been a major concern in the wood industry. Austrian companies and research institutes excel internationally in this field. In line with this guiding principle, SPG in working on the development of WPC/FPC applications and appropriate solutions. Unlike the thermal recycling of timber waste and also with a view to reducing tropical woods, the material is developed specifically to meet your requirements by using various natural materials with the addition of stabilizing polymers. The WPC products are distinguished by material strengths approximating hardwood, maximum weather resistance, excellent resilience, pleasant feel and timeless colours. Wood, rice, straw, coffee and even Tetra are used as the base materials for WPC/FPC applications.
Sealing/foaming/siding 
In addition to designing WPC tooling for decking, siding and fence systems as hollow or solid sections, SPG possesses particular strengths in extrusion for foam, siding and sealing profiles. Foamed and varied profile types of siding panels are realized based on highly detailed empirical values.
The extrusion of sealing profiles for rigid and soft PVC is a special area.
SPG pools its expertise in the high-quality extrusion plant for manufacturing sealing profiles and completes SPG's extensive range of services relating to tool and machine technology.
