POTENZA-III Servo Toggle Series
Potenza series with the continuous improvement to keep pace with the market demand, providing huge options and turnkey project solutions for all needs.
OVERVIEW
About POTENZA Toggle-Type Series
The POTENZA series is LK's toggle-type injection molding platform, built specifically for high-precision, high-volume manufacturing of medium-sized plastic parts. Spanning three progressive tiers — Potenza-A, Potenza-II, and Potenza-III — the series gives manufacturers a clear upgrade path from cost-optimized production to advanced, Industry 4.0-ready automation, all within the same 800-2,500 kN clamping force range (80-250 tons).
The Potenza-A series forms the advanced edition baseline, featuring CAE-optimized platen structures for even stress distribution, dust-proof dual linear guide rails, and a 12.1-inch HMI supporting eight languages with native OPC-UA connectivity for Industry 4.0 integration. Screw geometry improvements in this tier boost plasticizing capacity by 10% while reducing material degradation and surface defects like black spots and yellowing.
The Potenza-II series targets cost-optimized, high-precision mass manufacturing through a vector torque management system with full double closed-loop control over speed and pressure. European-imported electronic ruler scales maintain precision down to 0.1mm across mold-clamping, injection, and ejection movements — critical for industries like toy manufacturing and lighting components where dimensional consistency across thousands of cycles is non-negotiable.
The Potenza-III series is the most structurally refined tier, with finite-element-optimized clamping platens that minimize deformation under tonnage, an arch-designed injection carriage for stability, and zero-wear linear guide rail crossbeams replacing traditional sliding shoes. This tier suits manufacturers who need maximum precision and minimal long-term wear across continuous, high-tonnage production runs.
Across all three tiers, POTENZA machines serve toy and recreation manufacturing, furniture and domestic goods (handles, chair components, storage containers), home appliance accessories (trim plates, knobs, bezels), caster and hardware production, and lighting infrastructure (covers, sockets, reflectors).

Frequently Asked Questions
Potenza-A is the advanced edition baseline with CAE-optimized platens and Industry 4.0 OPC-UA connectivity. Potenza-II adds vector torque closed-loop control and European electronic ruler scales for 0.1mm precision. Potenza-III is the most structurally refined tier, with finite-element-optimized clamping and zero-wear linear guide rail crossbeams for maximum long-term precision.
All three POTENZA sub-series span 800 kN to 2,500 kN (80 to 250 tons), covering models PT80 through PT250 (or PTA/PT-III equivalents) depending on the tier selected.
POTENZA machines are widely used in toy and recreation manufacturing, furniture and domestic goods, home appliance accessories, caster and hardware production, and lighting infrastructure components.
Yes, particularly the Potenza-A series, which features native OPC-UA protocol support for direct integration with modern industrial management software, plus modular interface capacity for manipulators, core-pulling, and hot-runner systems.
The Potenza-II series uses European-imported electronic ruler scales that maintain precision down to 0.1mm across clamping, injection, and ejection movements, making it suitable for applications requiring strict repeat-weight consistency like toy manufacturing.
The Potenza-A's 12.1-inch HMI supports Chinese, English, French, Russian, Spanish, Portuguese, Vietnamese, and Turkish, making it suitable for global manufacturing operations.
