Frequently Asked Questions

What parts are best suited for 50-150 ton injection molding machines?

Small tonnage machines (50-150 tons) are ideal for small to medium parts with projected areas under 30-50 square inches. Common applications include medical components, electronic housings and connectors, caps and closures, precision technical parts, and high-cavitation molds for small consumer products.

What are the advantages of used 50-150 ton injection molding machines?

Smaller tonnage machines offer lower purchase and operating costs, smaller footprint, faster cycle times, lower energy consumption, and excellent precision. Used machines in this range from quality brands like Arburg, Engel, and Milacron offer exceptional value for precision molding applications.

How do I choose between 50, 100, and 150 ton machines?

Choose based on your part's projected area and the material being molded. General rule: 2-5 tons per square inch of projected area. A 50-ton machine handles parts up to ~15 sq in, 100-ton up to ~30 sq in, and 150-ton up to ~50 sq in. Also consider future growth and mold requirements.
