Ningbo Konger Machinery K-TEC series servo energy-saving injection molding machines are dedicated molding equipment developed for precision thin-wall electronic parts such as keycap brackets of desktop and laptop keyboards. Compatible with ABS material, it supports multi-cavity molding, short cycle time and high-efficiency mass production, delivering an integrated injection molding solution with high precision, stability and yield rate for keyboard structural components.

 Industry Application: Precision Injection Molding of Keycap Brackets
Keycap brackets (scissor feet/support frames) for laptop and desktop keyboards are ultra-thin, miniature and high-precision parts.
- **Material**: ABS engineering plastic, featuring high rigidity, toughness, stable dimension and controllable cost
- **Structure**: Thin wall thickness of 0.3–0.6 mm, complex buckles, micro assembly positions and multi-force bearing structures
- **Precision Requirement**: Dimensional tolerance ±0.02～±0.05 mm, strict standards for flatness, concentricity and fitting clearance
- **Production Challenges**: Difficult multi-cavity balance, frequent warpage, short shot and burr defects, long cycle time and low yield rate

Konger K-TEC series achieves in-depth optimization in mechanical rigidity, injection response, control accuracy and clamping stability, fully meeting mass production demands of keycap brackets.

 Core Advantages for Keycap Bracket Production
Ultra-rigid Clamping Structure for Undistorted Precision Molds
Reinforced high-strength platens meet European precision machinery deformation standards, preventing mold displacement and abrasion during long-term operation.
Optimized five-point linkage ensures smooth and fast mold opening and closing, compatible with high-cavity molds of 16, 32 and 48 cavities.
High-rigidity frame minimizes vibration during high-speed clamping, guaranteeing consistent quality of multi-cavity products.

High-speed Precision Injection System for Smooth Thin-wall Filling
Servo high-speed injection reaches 150 mm/s, far exceeding 90–95 mm/s of conventional machines, rapidly filling ultra-thin cavities and eliminating short shots, flow lines and cold marks.
Precision closed-loop control realizes real-time accurate adjustment of injection pressure, speed and position with repeat accuracy of ±0.1%, keeping tiny weight deviation among cavities.
Custom small-diameter high-length-diameter ratio screw ensures uniform ABS plasticization and steady temperature, avoiding material scorching, silver streaks and degradation.

High-efficiency Multi-cavity Production with Improved Capacity
Servo energy-saving system cuts power consumption by 25%–50% compared with traditional equipment, lowering long-term production energy costs.
Fast mold cycling, low-pressure mold protection and efficient ejection shorten single cavity cycle time by 15%–25%. Daily output reaches tens of thousands pieces for 32-cavity and 48-cavity molds.
Modular injection design enables rapid mold switching with different cavity quantities, supporting flexible multi-purpose production.

ABS-oriented Optimization for Higher Yield Rate
Precision temperature control system maintains barrel and nozzle temperature accuracy within ±1℃, stabilizing ABS plasticization, reducing internal stress and warpage.
Low-pressure clamping and precision venting eliminate burrs, flash and scorching caused by trapped air, simplifying post-processing work.
Intelligent control system features strong anti-interference capability and fast operation. Multiple sets of mold parameters can be saved with one click for quick mold change and steady product quality.

 Typical Application Scenarios
- Laptop keycap brackets (scissor foot brackets, X-structure brackets)
