Key Features

Built for Precise, Efficient Molding

Features that apply across the INJ series, based on approved technical data.

Repeatable Precision
Mold opening and closing position repeatability of ±0.5 mm and shot weight repeatability of 0.7%–0.3%.
Servo-Hydraulic Drive
Servo pump control with closed-loop pressure and speed control, a 30–50 ms response, and a 175 bar system pressure.
Twin-Toggle Clamping
A twin-toggle clamping unit with center-reinforced platens and T-slot plus threaded-hole platens as standard.
Adaptable Plasticizing
Several screw diameters per model, with electric plasticizing, electric injection, or accumulator injection available as options.

Clamping Unit

Twin-toggle clamping structure
T-slot plus threaded-hole platens as standard on all models
Center-reinforced moving and fixed platens that concentrate clamping force on the mold
Differential circuit for fast mold opening and closing
European-style ejector design for easy ejector pin removal and maintenance
Lengthened and widened slide guides for platen parallelism and repeat positioning
Self-lubricating steel and copper bushings

Injection Unit

Balanced twin-cylinder injection with balanced twin carriage cylinders
High-rigidity injection seat on precision linear guides
Guide-column carriage design to prevent melt leakage at high speed, pressure, and back pressure
Position-regulating screw design for consistent shot weight
Non-contact solid-state barrel temperature control from the feed throat
Roller-type slide for easier material changes
Screws available in different diameters, wear-resistance grades, geometries, and mixing designs

Hydraulic System

Servo pump control with an internal gear pump and closed-loop pressure and speed control
30–50 ms response and 175 bar system pressure
High-performance hoses with DIN-standard hydraulic fittings and no welded pipe joints
Modular hydraulic valve block with an optimized hydraulic layout
Servo pump control without overflow heating, combined with a built-in cooler to reduce cooling water use

Control System

Large color-screen controller as standard: 8-inch on INJ-100 to INJ-350, 12-inch from INJ-420
Statistical process control (SPC) quality management as standard
Action monitoring, production data monitoring, and fault alarm display
Optional Euromap 12 and Euromap 67 robot interfaces

Machine Manufacturing

Factory-Direct Injection Molding Machines

Machines are manufactured and supplied factory-direct, with INJ Mold Pro as your single point of contact from selection to shipment.

Injection Molding Machine Manufacturing
INJ Mold Pro manufactures injection molding machines for plastic part production, built to the configuration agreed for each project.
Machine Configuration & Application Matching
The injection unit, clamping unit, and controls are configured to suit the molding application, the plastic material, and the production requirements.
Mold–Machine Integration
Machines are matched to the proposed injection mold, so the mold can be installed, connected, and run together with the required auxiliary equipment.
Factory-Direct Supply
Machines are supplied factory-direct, with quotations, production updates, quality review, and shipment arrangements handled through INJ Mold Pro.

Machine models, specifications, availability, and commercial terms are confirmed in the quotation for each project.

Mold Compatibility

Matched to Your Mold

Each machine is configured around the proposed injection mold. These checks make sure the machine and the mold fit together.

Proposed Mold & Dimensions
Mold width, height, thickness, and weight are checked against the machine's platen size and mold mounting capacity, starting from the proposed mold design.
Mold Opening & Installation
The opening stroke and daylight must allow the part to be removed, and the mounting, locating, ejection, and cooling connections must suit the mold.
Clamping Force & Tie-Bar Spacing
The clamping force must hold the mold closed against injection pressure, estimated from projected area, wall thickness, flow length, and material, and the mold must fit between the tie bars.
Machine–Mold Compatibility
Nozzle and locating ring, ejector layout, and any hot runner or core-pull connections are checked so the mold can be installed and run on the selected machine.

Selection checks are carried out for each project, based on the proposed or existing mold.

Application Matching

Matched to Your Part and Production

The plastic material, the part, and how it will be produced decide how the machine is specified and configured.

Plastic Material & Injection Unit
Processing temperature, screw design, and material drying or handling requirements determine how the injection unit is specified for the plastic being molded.
Shot Capacity & Plasticizing
The combined weight of parts and runner sets the shot size, and the production rate sets how much material must be plasticized, each with a sensible margin to the machine's capacity.
Production Application & Requirements
Production quantities, operating schedule, process monitoring, and automation such as part removal influence the control system and the machine configuration.
Auxiliary Equipment & Production Setup
Mold temperature control, hot runner control, material handling, and part handling need compatible interfaces, and the site's power, cooling water, compressed air, and floor space affect the configuration.

The final machine configuration, specifications, availability, and commercial terms are confirmed for each project.

Mold & Machine

Where Machine Selection Meets the Mold Workflow

Machine requirements are defined alongside the mold, using information from the mold engineering workflow rather than repeating it.

Tooling Proposal
The proposed mold solution, including cavity count, runner configuration, and gate design, sets the starting point for the machine requirements.
Mold-Flow Analysis
The mold-flow analysis estimates how the proposed design fills, which helps confirm the injection and clamping requirements the machine must meet.
Complete Production Solutions
Where the machine is supplied together with the mold, auxiliary equipment, and production setup, the project is delivered as a turnkey production solution.

The tooling proposal and the mold-flow analysis are stages of the shared 11-stage mold workflow, described in full on the Manufacturing Capabilities page.

See the full manufacturing process

What to Prepare for a Machine Inquiry

Intended plastic product and its application
Proposed or existing mold information, such as dimensions, weight, and cavity count
Part dimensions and approximate part weight
Plastic material, including the grade if known
Expected production requirements, such as quantities and operating schedule
Preferred automation level and auxiliary equipment needs
Destination market and site requirements, such as power supply and floor space
