This automatic gate-cutting machine for injection-molded parts is designed to automatically remove gates/sprues from a wide range of products—including plastic components for home appliances, automotive parts, 3C electronics, and medical consumables. Integrating automatic feeding, positioning and clamping, multi-axis servo cutting, scrap separation, and finished-part unloading, it replaces traditional manual nipper operations. This eliminates common issues such as low efficiency, uneven cuts, and inconsistent quality, helping injection molding enterprises standardize post-molding processes while reducing costs and increasing efficiency.
The equipment features automatic feeding via vibratory bowls, conveyor belts, or integration with injection molding machine robots. Using a precision rotary table or linear slide, it executes workpiece positioning, multi-angle cutting, scrap collection, and sorted output of finished parts—all without manual intervention. A single operator can monitor multiple machines simultaneously, significantly reducing labor reliance and enabling a seamless workflow from injection molding to gate cutting and subsequent processes.
Built with a high-rigidity frame and an independent servo drive system, the machine delivers stable, powerful cutting performance. It supports various materials (ABS, PP, PC, PA, etc.) and gate types (side gates, pin-point gates, submarine gates) using either cold-cutting (punching) or hot-cutting processes. This ensures clean, burr-free, and non-whitened cut surfaces with a repeatability accuracy of ±0.05mm. Designed for stable 24/7 operation, the system maintains a defect rate below 0.2%, ensuring consistent product quality across batches.
Equipped with a PLC and industrial touchscreen, the machine stores specifications and cutting parameters (path, speed, pressure, angle) for hundreds of part types, allowing for one-touch production changeovers. Safety features include automatic tool alignment, light curtains to prevent hand injuries, and real-time torque monitoring; the system automatically halts and triggers audio-visual alarms upon detecting anomalies. Flexible configuration options—such as multi-axis robotic arms or modular units—allow it to handle complex geometries, including flat surfaces, curved surfaces, and deep cavities.
The cycle time for a single cut is just 2–5 seconds (depending on part structure and the number of gates), representing a 6- to 10-fold increase in efficiency compared to manual nipper operations, with a single-machine daily output of 30,000 to 50,000 units. It significantly reduces operator hand fatigue and the risk of workplace injuries while cutting labor costs and expenses associated with reworking defective parts, resulting in an overall reduction in operating costs of more than 50%.
Centered on precision servo control and stable cutting action, this automatic gate-cutting machine for injection-molded parts ensures that every product meets ideal aesthetic standards regarding gate residue. Choose this solution to eliminate the inconsistencies and efficiency bottlenecks of manual trimming, allowing your products to move seamlessly and efficiently to the next stage of production and into the market with a uniform, high-quality finish.
