Why Choose Us
Vertical Molding Expertise
The equipment range focuses entirely on vertical injection molding technology designed specifically for insert molding and overmolding applications. The vertical layout maintains gravitational assistance and direct operator or robotic access to the lower mold half.
Process-Based Configuration
Machine selection evaluates insert geometry, mold dimensions, resin rheology, production sequence and automation integration simultaneously. This comprehensive approach determines the optimal clamping force, injection unit size and table arrangement.
Technical Support
Engineering assistance encompasses technical application review, customized machine configuration, layout planning, installation guidance and onsite or remote commissioning support.
Export Preparation
All machinery undergoes strict preparation for international transport utilizing reinforced export-grade wooden packaging designed to withstand rigorous sea and air freight handling conditions.
Built for Metal Insert Molding
Direct Mold Access
The lower mold station remains fully exposed and accessible for insert preparation before each molding cycle begins. Operators or automated loading fixtures can position metal components directly into dedicated precision cavities safely.
Controlled Insert Positioning
Cavity geometry, dedicated locating pins and mechanical holding elements are engineered around the exact shape and orientation of the insert. This establishes precise dimensional registration prior to mold closing and resin injection.
Plastic Encapsulation
Thermoplastic material flows smoothly around the precisely positioned metal insert to form a unified structural assembly. The finished molded part effectively combines the electrical, mechanical or structural performance of the metal insert with the protective plastic body.
Machine Configurations
Fixed Table
The mold remains in a single stationary working position throughout the entire molding cycle. This layout suits production processes where insert loading and finished part removal are performed safely at the same primary station.
Slide Table
The mold base moves horizontally between the injection station and the loading station. This mechanical separation isolates manual insert preparation from the high-temperature injection area, establishing a secure and repeatable operating sequence.
Rotary Table
Two-station and four-station rotary table configurations organize insert loading, resin injection, and part removal around a continuously rotating worktable. The station arrangement matches the specific cooling and handling duration of the production run.
Tie-Barless Layout
The open clamping zone removes traditional tie-bars to provide unobstructed perimeter access around the mold area. This specialized layout accommodates oversized tooling, bulky loading fixtures or complex multi-axis automation systems.
Metal Inserts and Applications
Terminals and Contacts
Terminals, contact pins and electrical leads are positioned securely within dedicated cavities for high-precision electronic connectors. Specialized tooling controls positional tolerance during high-pressure injection.
Wires and Cables
Exposed wire ends and complex cable assemblies are restrained using customized holding fixtures. The fixture maintains proper cable routing angle and insert depth during mold closing and encapsulation.
Bushings and Threaded Inserts
Metal bushings and threaded fastening inserts are overmolded into thermoplastic components to provide durable metal threads. Mold design carefully accounts for insert dimensions, locating surfaces and pull-out resistance.
Stamped Components
Custom stamped metal parts are integrated directly into molded structures where high mechanical strength, defined electrical grounding or structural mounting points are required.

Clamping Force
Clamping tonnage is calculated based on the projected surface area of the molded part, injection pressure, material viscosity and mold parting line requirements.
Mold Dimensions
Mold length, width, overall height, platen bolt pattern and open daylight clearance are reviewed together to ensure adequate physical space for the chosen insert loading method.
Injection Requirements
Resin type, calculated shot volume, material filling behavior and processing melt temperatures are analyzed carefully to select the correct screw diameter and injection pressure.
How to Select the Right Machine
Define the Insert: Analyze insert material composition, physical dimensions, mass, orientation tolerances and locating surfaces. These parameters dictate the necessary cavity design and loading mechanism.
Review the Mold: Evaluate mold dimensions, cavity count, runner layout, mechanical or hydraulic ejection systems and working clearances in coordination with the machine specifications.
Set the Production Rhythm: Evaluate total production volume and cooling time requirements to determine whether a fixed-table, slide-table or rotary-table machine layout delivers optimal throughput.
Plan the Automation: Establish whether insert placement and part extraction will be executed manually, using operator-loading fixtures, or via full robotic automation to define required machine safety interfaces.
Automation Options
Insert Loading
Pneumatic fixtures and automated pick-and-place handling systems position terminals, pins, bushings and wires prior to mold closing. The automation method aligns with insert geometry and cycle time constraints.
Part Removal
Finished overmolded parts can be extracted manually by the operator or automatically using mold drop-out, mechanical sweeps and robotic end-of-arm tooling.
Cycle Coordination
Slide-table and rotary-table systems separate loading, molding and unloading into concurrent production phases, maximizing machine utilization and operator safety.
Safety Interface
Automation hardware integrates directly with machine PLC controls, optical light curtains, mold protection sensors and emergency stop circuits to maintain operator safety.
Applications Across Industrial Production
Automotive Components
Applications include complex automotive wiring connectors, electrical terminals, under-hood sensor housings, heavy-duty relays and hybrid metal-plastic subassemblies.
Electrical and Electronics
Duis tristique sollicitudin nibh sit amet Power plugs, multi-pin connectors, circuit breaker contacts and insulated terminals are manufactured with tightly controlled insert positioning for reliable electrical performance.
Cable and Wire Products
Specialized wire harness overmolding applications utilize precision clamping fixtures that maintain exact cable orientation and strain relief during the plastic injection cycle.
Industrial Components
Threaded brass inserts, steel mounting bushings and structural reinforcement plates are integrated seamlessly into thermoplastic housings for industrial machinery and control devices.
Machine Inspection: Clamping movement accuracy, injection pressure response, hydraulic stability, PLC control functions and safety interlock systems undergo rigorous pre-shipment testing.
Quality Control: Complete machine assembly and operating conditions are verified thoroughly against agreed technical specifications prior to crating and release.
Compliance: Electrical schematics, safety guarding standards and regional compliance documentation are verified according to the destination market requirements.
Production Verification: Insert drawings, mold structural designs, resin data sheets and clamping tonnage calculations are reviewed prior to final machine build to ensure process readiness.
Mold Matching: Machine layout and platen dimensions are engineered around existing or new mold designs, accounting for cavity arrangement, core pull cylinders and ejection strokes.
Table Selection: Fixed, slide and rotary table mechanisms are chosen to match the required operator interaction level, cycle time targets and workspace constraints.
Process Requirements: Specific resin behavior, required injection speed, clamping tonnage and cooling parameters are integrated into the final machine control program.
Production Layout: Operator ergonomics, material staging positions, mold loading direction and peripheral automation clearances are coordinated to establish an efficient shop floor layout.
