Plastics technology comprises injection moulding machines, extruders, blow moulding machines and tool changing systems, which have to combine high forces with precise positioning. Drive components there are often exposed to aggressive cleaning agents, elevated temperatures and contact with plastic melts. Food contact or cleanroom requirements can place additional demands on materials and lubricants.
Compared with steel versions, plastic gears made of acetal (Hostaform) offer advantages such as quiet running, self-lubrication and corrosion resistance. In certain applications they can sensibly replace steel components while reducing weight and costs.
WMH Herion offers an extensive range of spur gears, bevel gears and racks in plastic (acetal/Hostaform) that meets the specific requirements of plastics technology. The parts are corrosion-resistant, self-lubricating and suitable for use in damp or chemically loaded environments.
For screw and linear drives in injection moulding and extrusion systems, WMH Herion supplies lead screws, ball screws and matching screw jacks. The stock programme ensures short delivery times even for more complex procurement requirements.
For plastics technology, WMH Herion offers spur gears and racks in acetal/Hostaform, screw jacks and lead screws for linear drives as well as couplings for dynamic drive trains. Plastic gears are available from stock in various modules and tooth counts.
WMH Herion supplies drive assemblies for linear systems and screw drives in plastics machinery that are designed for the customer’s specific force and positioning requirements. Plastic and steel components can be combined as required.
What distinguishes WMH Herion as a partner?
Plastics processing machines, whether extruders, injection moulding machines or calender systems, run their drive trains under high torques and in continuous operation. WMH Herion supplies spur gears, couplings and gear units in versions that withstand these loads permanently. The broad stock programme with over 12,000 standard items and in-house custom production cover series requirements as well as special designs.
Because design and sales work under one roof at WMH Herion, you receive technical feedback directly, whether on material suitability, backlash behaviour or modification options. ISO 9001 certified, proven in plastics technology and in more than 40 further industries worldwide.
What advantages do plastic gears offer over steel versions in plastics technology?
Plastic gears made of acetal (Hostaform) are self-lubricating, quiet-running and resistant to many chemicals and moisture. They are particularly suitable for applications with light to medium loads in which corrosion resistance or noise reduction is the priority.
Are screw drives for injection moulding machines available in the standard programme?
Yes. WMH Herion offers lead screws, ball screws and screw jacks in various sizes and leads for linear drives in plastics machinery. The components are available from stock and can be cut to length and assembled on request.
Does WMH Herion also supply complete assemblies?
Yes. In addition to individual components, we offer assembled handling axes and complex multi-axis systems, fully assembled, tested and ready for use.
How quickly are standard items available?
Most items from the stock programme are available immediately and are delivered within a few working days. For custom-made solutions, we discuss the delivery time individually.
