FOMTEC FT-KC Single-Station Two-Color Vertical Injection Molding Machine

— Dual Injection System · Professional Platform for Single-Station Two-Color Molding

📌 I. Product Overview

The FOMTEC FT-KC Single-Station Two-Color Vertical Injection Molding Machine is a professional model developed by FOMTEC specifically for molding two-color or two-material plastic products. Featuring a vertical clamping and dual injection system core architecture, it achieves simultaneous injection and one-shot molding of two materials or two colors in a single-station layout.

The FT-KC series is especially suitable for toothbrush two-color overmolding products — with inserts placed vertically and two materials injected simultaneously into the mold cavity. Practical recommendations from FOMTEC injection molding engineers have fully validated the professional suitability of this model for such applications.

⚙️ II. Core Technical Advantages

🏗️ 1. System Mechanism Design – Vertical Clamping + Dual Injection System

The FT-KC series features a mechanism design combining vertical clamping with a dual injection system.

Vertical clamping positions the mold facing upward, making insert loading intuitive and convenient with no blind spots for the operator — especially suitable for two-color overmolding of insert-type products. This structural feature makes the FT-KC series an ideal production platform for toothbrush two-color overmolding products — with inserts placed vertically and two materials injected simultaneously into the mold cavity.

Dual injection system equips the machine with two independent injection units, capable of simultaneously injecting two different colors or two different material properties into the mold cavity, achieving one-shot molding of two-color / two-material products.

🔧 2. Injection Unit – Monoblock Dual-Cylinder Injection Design

The FT-KC series injection unit features a monoblock dual-cylinder injection design with two core advantages:

• Smooth Operation: The monoblock structure ensures coordinated and synchronized movement of the dual injection cylinders, providing stable and reliable operation

• High Injection Precision: Precision manufacturing and assembly guarantee accuracy and consistency for every injection shot

This design enables the FT-KC series to maintain stable molding quality throughout high-volume production of two-color / two-material products.

⚡ 3. Dual Hydraulic System – Independent Control, Precise Coordination

The FT-KC series is equipped with a dual hydraulic system that independently controls the two injection units. The two injection units are driven by separate hydraulic circuits, enabling both coordinated one-shot two-color / two-material molding and independent adjustment of injection pressure, speed, and other parameters as required by the process. This design ensures precise control and mutual non-interference of the two materials during the injection process.

🎯 4. Electrical Control System – HITECH Control + Electronic Scale + PID Temperature Control

The FT-KC series adopts an advanced electrical control system with the following core features:

Taiwan HITECH Control
Uses the well-known HITECH control system, offering stable and reliable performance with a user-friendly interface.

Linear Displacement Electronic Scale (Position Sensor) Control
Both clamping and injection systems are controlled by linear displacement electronic scales for convenient setting and effective precision assurance. The electronic scales provide high-precision position feedback, ensuring accuracy and repeatability for every action.

P.I.D. Temperature Control System
Barrel temperature is controlled by a P.I.D. temperature control system with stable and precise temperature regulation across all zones, ensuring consistent melt quality.

🔄 5. Process Sequence – Complete Two-Color Molding Action Cycle

The FT-KC series follows this complete molding action sequence:

Mold Close → Unit 1 Advance (Unit 2 Advance) → Unit 1 Injection (Unit 2 Injection) → Unit 1 Hold Pressure (Unit 2 Hold Pressure) → Unit 1 Plastication (Unit 2 Plastication) → Unit 1 Screw Retraction (Unit 2 Screw Retraction) → Unit 1 Carriage Retract (Unit 2 Carriage Retract) → Mold Open → Ejector Forward → Ejector Retract

Process parameters for the two injection units can be set independently — injection speed, injection pressure, holding time, shot size, and other parameters for each injection system can be configured separately without interference. This feature enables the FT-KC series to flexibly accommodate different material combinations, ensuring each material is injected under optimal conditions.

🏭 III. Typical Applications

🪥 Toothbrush Two-Color Overmolding Products

FOMTEC injection molding engineers have clearly stated: “Toothbrush two-color overmolding products are ideally suited for production on this type of injection molding machine, with inserts placed vertically and two materials injected simultaneously into the mold cavity.”

This application fully demonstrates the core value of the FT-KC series:

• Vertical Insert Placement: Accommodates long-shaped inserts such as toothbrush handles

• Simultaneous Two-Material Injection: Hard plastic skeleton and soft rubber grip layer molded in one shot — no secondary transfer required

• One-Shot Two-Color Molding: Reduces quality issues caused by thermal contraction mismatch and significantly shortens production cycles

🎨 Other Two-Color / Two-Material Products

The FT-KC series is also suitable for molding other two-color or two-material plastic products, such as tool handles, electronic consumer product buttons, and daily-use two-color items.

🏢 IV. FOMTEC’s Multi-Color & Multi-Material Technical Strength

Since producing its first two-color three-station rotary table vertical injection molding machine in 2005, FOMTEC has accumulated nearly 20 years of technical expertise in multi-color & multi-material molding. The multi-color / multi-material product line includes:

FOMTEC designs and manufactures injection molding machines with clamping force ranging from 15 to 650 tons and shot capacity from 35 g to 8000 g, providing precisely matched machine configurations based on specific product requirements.
