Toggle Injection Moulding Machine

At CLF, a trusted leader among global plastic injection molding machine manufacturers, we proudly introduce the Outward Toggle Type Injection Molding Machine. Engineered for high-precision, high-rigidity, and deep-cavity applications, the TWII Series leverages an innovative external toggle mechanism to deliver superior mold protection, enhanced product quality, and flexible manufacturing solutions.

Covering clamping forces from 100 to 5000 tons, the TWII Series empowers manufacturers to achieve high-performance production with minimal platen deformation, extended mold opening strokes, and intelligent energy-saving options.

What is Toggle Injection Molding?

Toggle injection molding utilizes a mechanical toggle system to generate clamping force during the molding process. Unlike hydraulic ram clamping, the toggle mechanism concentrates force at the center of the platen, ensuring uniform pressure distribution, minimal platen deformation, and rapid mold opening and closing cycles. This makes toggle systems ideal for high-speed, high-precision, and deep-cavity applications across various industries.

The TWII Series specifically features an outward toggle design, where the toggle arms move outward instead of inward. This design innovation reduces the overall space requirement, enhances mold accessibility, and enables better accommodation of wide, deep, and long molds—perfect for industries such as automotive bumper production.

Performance at a Glance

Performance may vary depending on mold design, material properties, and cycle settings. For full specifications including 250t, 500t, 1100t, and 3500t models, please download our detailed spec sheet.
