Advantages of Double Color Injection Molding Machine

Cost-Effectiveness & Efficiency

Because only one machine cycle is used, 2 shot molding allows multiple components to be made with a single tool. This also eliminates the need to join components after the molding process, leading to less operating and labor costs. Because components are joined during molding there are fewer overall components in the finished assembly, which cuts costs in the finished product for development, engineering, and validation.

Better Part Quality

Two shot injection molding allows for tighter tolerances than other molding processes and delivers a high level of accuracy and repeatability — all of which reduce scrap rates. The process eliminates some of the need for secondary processes such as sonic welding or assembly. Because the components are made and joined in the same step, there are far fewer instances of misalignment when compared to over-molding or a more traditional insert process.

Versatility

Two shot molding expands design possibilities and allows for complex mold designs that integrate multiple materials for functionality that can’t be reached through older molding processes. This leads to enhanced product features and appeal, with the addition of tactile, ergonomic, and aesthetic characteristics. Use multiple colors to add a distinctive look or reinforce brand image on specific components.

Daily Inspection Checklist for Double Color Injection Molding Machines

Mold Height

Determining the proper mold height is arguably one of the most critical starting points when a new injection molding machine setup is required. During this process, the machine clamping force is calibrated to meet the particular mold dimensions.

Mold Heater/Cooling

Mold heater/cooling connections bring the injection mold to the needed process temperature. During this phase, energy will be added or removed from the mold. To ensure the process temperature is achieved, water or oil will be directed through the mold with at least one in and one out connection – referred to as a set.

Hot Runner Connections

Some injection molding machine brands will be designed with a “hot runner system.” In these instances, there will be a designated runner that ejects from the injection mold during the final ejection of the plastic part.

Ejector Safety Sensor

Some designs will require the use of ejector pins to function correctly. If these ejector pins are installed incorrectly, they can be damaged during the injection mold closure process. One example of mold types requiring ejector pins is those with mounted slides.

Core Pull Connections

In some scenarios, the part geometry does not allow plastic parts to be ejected freely from the mold. It is important to equip the mold with retractable cores when this occurs. Often, these cores will remove the part with the assistance of hydraulic or pneumatic cylinders.

Daily Inspection Checklist for Double Color Injection Molding Machines

Power, control panel, and safety devices

Check emergency stops, door interlocks, alarms, and indicator lights at the start of each shift. Confirm the HMI shows normal status and no error codes before production.

Hydraulic and pneumatic circuits

Look for oil leaks, air leaks, and pressure drops. Confirm accumulator and air supply pressures stay within the range defined by your machine manual.

Plasticizing, injection, and mold area

Inspect the nozzle area, screw movements, and tie bars. Keep the platen, mold parting line, and ejector area clean and free of resin drool and dust.

Two-color alignment and rotation function

For two color and multi color vertical machines, verify rotary table or indexing function is smooth and aligned, so both shots meet correctly in the cavity.
