Fast mold closing and slow low-pressure mold locking action device can ensure mold safety, fast speed and increase output. The injection device and the mold locking device are on the same vertical centerline, and the mold is opened and closed along the up and down direction, with a small floor area. Bottle Cap Injection Molding Machine is easy to realize insert molding, the die surface is upward, and the insert is easy to put in and position.
Bottle Cap Injection Molding Machine is the main molding equipment for making bottle caps of various shapes with plastic molding molds. It has the function of low-voltage safety protection. The uniquely designed mold closing technology can protect personal safety and ranks in the forefront of the same industry. If there is foreign matter blocking between the upper and lower molds, the mold will not be locked forcibly, and the mold will be opened automatically. It is conducive to maintaining the accuracy of machinery and die for a long time.

Key Features
Fast Cycle Times
Optimized hydraulic loops and high-torque plasticizing motors achieve production cycles of 2.5 to 4.5 seconds.
Servo-Hydraulic Efficiency
Equipped with high-response permanent magnet servo drive systems, reducing electricity consumption by 30% to 50% compared to conventional hydraulic systems.
Specialized Screw & Barrel Assembly
Nitrided or bimetallic screws are custom-configured for high-output HDPE and PP processing, ensuring uniform melt temperature and eliminating color streaking during rapid injection.
Rigid Clamping & Platen Design
Finite Element Analysis (FEA) optimized toggle system distributes clamping force evenly across the mold surface, preventing platen deflection and minimizing flash on cap threads.

Industrial Applications & Closure Types
Beverage & Water Closures
All melt-contact parts are compatible with food-grade resin processing, ensuring compliance with FDA and EU 10/2011 regulatory standards for food contact materials.
Dispensing & Flip-Top Caps
Precise core-pulling control for complex, multi-component, or hinged closures used in household chemicals, cosmetics, and edible oils.
Medical & Pharmaceutical Closures
Equipment configurations adaptable to Class 100,000 cleanroom layouts, meeting international sanitary and dimensional consistency compliance.
Upstream Automation: Centralized vacuum feeding, gravimetric masterbatch dosing, and desiccant drying for consistent resin conditioning.
Hot Runner Mold Integration: Full synchronization with high-cavitation, valve-gated hot runner molds for uniform thermal distribution and zero-leakage balancing.
In-Line Post-Molding Auxiliaries: Continuous rotary slitting and folding machines for tamper-evident (TE) bands, alongside high-barrier liner/wad insertion units.
100% Optical Vision Inspection: Multi-camera sorting systems inspecting 2,000+ caps/minute to automatically eject short-shots, flashes, and ovality defects.
Centralized System Control: Interconnected PLC networks (EtherCAT/Profinet) allowing full line monitoring and synchronization from a single control interface.
Global Brand Component Integration: To simplify global maintenance and ensure parts availability, we build our machines with industry-standard components: KEBA/Techmation controllers, Phase/Gefran servo drives, and Yuken/Rexroth hydraulic valves.
In-House CNC Machining: Critical structural components, including platens, toggles, and machine bases, are machined in-house on high-precision horizontal machining centers to maintain manufacturing tolerances within ±0.01 mm.
72-Hour Continuous Factory Testing: Every injection molding machine undergoes a mandatory 72-hour dry cycle running test and automated pressure holding tests before dispatch to eliminate early-stage component risks.
Metrology & Alignment: Laser interferometers and 3D coordinate measuring machines (CMM) are used to calibrate tie-bar alignment and clamping parallelism before leaving the assembly floor.
