Two Color Plastic Injection Molding Machine
MINHUI two-color injection molding equipment supports projects combining two colors or two materials in a part. Select the injection units, material pair, transfer arrangement and tooling together; a rotary table alone does not establish two-color capability.
Two Color Injection Molding Machine Description
- The upper template is equipped with two upper molds, and the rotary has two lower molds. When forming, the disc is rotated 180 forward and reverse. It can complete two-color two-material injection molding, or over-molding injection molding machine two-color machine.
- Vertical mold clamping, additional disc, and two independent injection units (independent hydraulic oil circuit) clamping force as stated in the selected model sheet and quotation, using complete computer control, low and high hydraulic system, more suitable for the production of general or special Two-color (two-material) molding.
- The turntable adopts hydraulic motor speed control, optional servo motor drive, mechanical positioning device to ensure the accuracy of positioning and the mold and ensure that the molding mold is accurately and quickly closed.
- Two sets of independent mold clamping systems are also available, the movable templates are separated, and different molds can also be formed in two colors and two materials.
- Clamping force: confirm the selected model and quoted configuration.
- Injection capacity: confirm the screw option, material basis and required shot volume for each injection unit.
- Vertical calmping, vertical injection.
- Rotation stability mult-station design, accuracy of rotation and positioning, convenient taking and placing device.
- We can upgrade to servo motor for customer’s needs.
- Compare measured energy consumption under the actual part, mold, materials and complete cycle. No universal saving percentage is specified here.

How many types of two-color injection molding machines are there?
Two-color systems combine injection units with tooling and a transfer arrangement matched to the part. The exact mold count, station layout, nozzle arrangement and material-conditioning equipment depend on the selected configuration; they are not universal features of every two-color machine.
A two-color plastic injection machine is a kind of machine that can produce plastic products with different materials and different colors.
Two-color injection molding machine through the injection device and technology to inject two different materials into the same set of mold injection finished products.
The first and second molding stages must be coordinated with the transfer and tooling design. Confirm the proposed sequence, interfaces and acceptance criteria for the actual part.
The requirements of a double colour injection molding machine are relatively complex for the mold, and its structure and characteristics are different from those of single-color molds.
Types of two-color plastic injection molding machine
Review how the first molded component is positioned for the next injection stage. Ask for the proposed mold and transfer layout; a general machine-family description is not a configuration drawing.
Tooling review should cover support for the first component, interface sealing, alignment and deformation during the second injection. Confirm these with the mold designer and a representative trial.
The development of two-color plastic injection molding machine types
Potential applications include electronic housings, handles and other multi-component parts. Medical or other regulated applications require separate material, process and finished-product validation; an application example does not establish compliance.
Two-Color Machine Selection Questions
Is Two-Color Injection the Same as a Rotary Table?
No. A rotary table describes mold handling. Two-color molding also requires the appropriate injection units, controls and tooling. Compare this family with the rotary table machine family by complete configuration rather than the table name.
What Must Be Checked for Each Injection Unit?
Specify the material grade, required shot volume, screw option, injection pressure and processing conditions for each component. A single combined shot-weight number does not describe the capacity available from each unit.
Will Any Two Materials Bond?
No. Confirm material compatibility, the interface design and the required adhesion or retention test. Validate the proposed material pair and molding sequence with representative tooling and parts.
Which Published Documents Should Be Reviewed?
The parameter and platen links above are model-specific references. Match the selected press sheet, injection-unit sheet and station drawing to the quotation. Do not apply one model’s values to the entire family.
What Is Needed for a Useful Production Trial?
Provide both material grades, part drawings, component shot volumes, mold and transfer design, expected output and measurable acceptance criteria. Record complete-cycle time and reject rate under stated conditions. Use the vertical machine selection checklist for the remaining factory and tooling checks.
