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.

Single-Color Rice Washing Basket Mold (PP)

The single-color rice washing basket mold is manufactured using a carefully designed injection mold.

The product is produced using PP (Polypropylene) material, offering durability suitable for daily kitchen use.

One of the key functional features of the rice washing basket is the draining spout design,

allowing users to easily remove water after rinsing rice.

In mold design, it’s essential to ensure the draining spout area is formed with smooth edges to avoid scratching users.

Additionally, the basket body typically contains small drainage holes

that require precise mold machining to ensure uniform hole size and burr-free edges for smooth water drainage.

To meet customer customization requirements, this mold features replaceable logo inserts.

Regarding the gating system, to maintain a clean appearance for the rice washing basket,

this mold often utilizes a submarine gate or pinpoint gate feeding method.

This approach ensures the gate mark is automatically trimmed during ejection, leaving minimal visible residue.

YUEYI Mould pays attention to details,  striving to make every mold achieve optimal performance

and brand-distinctive rice washing baskets for our customers.
