At YUEYI, we specialize in advanced two color injection molding solutions.

One of our proven applications is the two color plastic screw mold

— designed to produce high performance screws that combine different materials or colors in a single, integrated part.

Mold Design & Manufacturing

Our two color screw molds are built for precision and longevity.

Key technical details:

Steel grade: Hardened H13 (HRC48-52) for high wear resistance and extended production runs.

Rotary or core-back two-color process to achieve seamless material bonding.

Precision thread geometry with tight tolerances for consistent screw performance.

Optimized cooling channels to ensure stable cycles and minimal warpage.

Let us help you develop a custom solution tailored to your product requirements.

Mold Specifications:

• • Mold Type: Single-color injection mold

  • Product: Small, medium & large lids

  • Cavity Number: 2+2+2 

  •  Core & Cavity steel: 1.2738HH

  • Gate Type: 6 tips valve gate 

  • Injection Machine: 280 ton

  • Product Material: PP

  • Surface Finish: Grain texture

We manufacture a single-color mold for producing three different lid sizes in one cycle.

The cavity layout is 2+2+2, This design improves production efficiency while keeping tooling costs reasonable.

The core and cavity are machined from 1.2738HH steel.

It ensures the mold runs reliably for long production runs with minimal maintenance.

We use a 6 tips valve gate. it also prevents stringing and drooling, which keeps the molding process clean and stable.

At YUEYI, we focus on practical, high-quality molds.

How to Make a Two-Color Kids Step Stool Mold (PP+TPE)

Mold Specifications:

Plastic Materials: PP + TPE

Cavity Number: 1+1

Steel for Core & Cavity: 1.2738HH

Gate Type: 4 tips HR point

Injection Machine: 400 ton  rotary table

 

A two-color kids step stool mold combines hard and soft materials in one product.

The hard part uses PP for strength and stability.

The soft part uses TPE for a non-slip, comfortable surface where children stand.

This mold is made with a 1+1 cavity layout.

One cavity molds the PP base, and the other molds the TPE overmold.

The injection machine has a 400-ton clamping force and a rotary table.

After the first shot (PP), the rotary table moves the preform to the second station.

Then the TPE is injected onto the designated areas.

This process creates a perfect bond between the two materials.

We use 1.2738HH steel for the core and cavity.

This steel offers excellent polishability, wear resistance, and uniform hardness.

It ensures long mold life and consistent part quality.

The 4-point hot runner system delivers precise material flow into each cavity.

It reduces waste and improves surface finish.

Cooling channels are carefully designed to shorten cycle time and prevent warpage.

Venting is also placed properly to avoid air traps.

Every detail is checked to ensure safe, durable step stools for children.

At YUEYI, we focus on practical, high-performance molds.

24 caveties single-color spout Mold

The single-color spout mold serves as both the sealing closure and the drinking spout.

The suction nozzle is made from PP. It provides  secure sealing and softness for comfortable use by children.

The nozzle features precise dimensional requirements to ensure a perfect fit with the pouch sealing film.

The runner system  uses hot runner.

Proper venting and cooling channel designs are essential for  preventing defects such as sink marks or warpage.

At YUEYI Mould, we focus on translating customer requirements into optimal production solutions.

Every new mold we design undergoes a rigorous trial molding and inspection process

to ensure all parts meet dimensional specifications and perform reliably in high-volume production.

If you are looking for a trusted partner for your spout molds,

please feel free to contact us for a quotation.

We look forward to supporting your project with quality, precision, and professional service.
