Used Horizontal Plastic Injection Molding Machines for Sale

Horizontal plastic injection molding machines are the most widely used configuration in the plastics industry. These machines (also known as horizontal injection moulding machines) feature a horizontal clamping unit where the mold opens and closes along a horizontal axis, allowing parts to drop by gravity for easy collection. Horizontal injection molding machines are available in toggle clamp, direct hydraulic, and two-platen configurations, ranging from 50 tons for small precision parts to over 6,000 tons for large automotive and industrial components.

When buying a used horizontal injection molding machine, key specifications to evaluate include clamp tonnage, shot size (oz), screw diameter, platen dimensions, tie bar spacing, and daylight opening. Toggle-clamp machines offer fast dry cycle times and are preferred for high-speed packaging and thin-wall applications. Direct hydraulic clamp machines provide uniform clamp force distribution and are ideal for large, flat parts. Two-platen machines save floor space while delivering high tonnage.
