Introduction: Innovation in Dual-Material Houseware Tooling

In the modern housewares market, consumers demand products that combine visual elegance with superior functional ergonomics. A prime example is the high-performance two color ice cube tray mold project—combining a durable, rigid PP frame with flexible, TPE soft bottoms for effortless ice release.

Engineered by Focare Mould, a premier two color mold maker and trusted China mold maker, Mold demonstrates how advanced 2K injection technologies optimize cycle times, prevent material bleeding, and lower per-unit manufacturing costs.

Molding Cycle & Ejection System Workflow

Achieving seamless high-speed production with a two color ice cube tray mold requires flawless kinematic synchronization during the rotary injection cycle. The detailed automated process includes:

1.1st Shot Injection (1S): Injecting the primary PP rigid structural frame.

2.Mold Opening & Core Rotation: Main mold opens; the core side rotates 180° via the rotary table mechanism.

3.2nd Shot Injection (2S): Mold closes; TPE resin is injected to overmold the soft-touch bottoms onto the PP frame.

4.Mold Opening & Runner Separation: Mold opens; 2S cold runner drops automatically or is retrieved via robot arm.

5.Precision Demolding & Ejection: Machine activates the 30mm stripper plate, combined with poppet air valves and angled air-assist blowers, ensuring damage-free release of the completed 2S product.

6.Continuous Cycle: Process repeats continuously for high-volume automated production.

Engineering Highlights & Technical Advantages of Focare Mould

As a specialized China mold maker, Focare Mould incorporates key engineering enhancements into Mold to overcome traditional dual-shot manufacturing bottlenecks:

1.Hot-to-Cold Runner Hybrid System: By utilizing a hot runner to cold runner three-plate mechanism, we achieve optimal thermal control at the gating points while ensuring clean, automatic runner separation during every cycle.

2.Advanced Air-Assist Ejection for Soft TPE: Flexible TPE soft bases tend to stick to core inserts due to vacuum suction. By integrating poppet air valves and angled air-assist blowers alongside a 30mm stripper plate, Focare Mould uses these features to assist part release; ejection performance is checked during mold trials.

3.High-Precision Rotary Alignment: Specifically designed to operate on rotary table injection machines like the FCS KN-200R and FB-250R, our tool alignment requires the resin shrinkage allowance and PP/TPE interface to be checked for the selected material grades.

Why choosing Focare Mould as your work partner?

Request a 2K ice cube tray mold quotation

For a project review, send your 3D tray drawing or sample, tray dimensions, cube layout, PP and TPE grades, annual production target and machine specification sheet. Tell us the required surface finish and where the flexible TPE should be positioned. If the finished tray will contact food, include the destination market and required material documentation.

The featured mold has 1+1 cavities and 718H steel at 30-33 HRC. Each material uses one hot runner tip feeding a cold runner. The listed testing machines are FCS KN-200R / FB-250R; confirm compatibility separately for your production machine. Discuss runner handling, ejection sequence and trial acceptance criteria before finalizing the tooling specification.
