Precision detail replication: Ideal for capturing fine features like facial expressions, textures, and contours common in soft toys.
Reduced defects: Eliminates flow imbalance, ensuring uniform TPU layer thickness and core alignment.
Flexible production: Perfect for small-to-medium batch runs of custom or niche toy designs.
Consistent melt flow: Maintains uniform TPU temperature, preventing material degradation or discoloration during the soft layer injection.
Eliminates cold runner waste: Reduces scrap and ensures the TPU material stays clean and hygienic, essential for children’s toys.
Balanced pressure delivery: Ensures complete filling of the mold cavity, even around the hard plastic core, avoiding air traps or incomplete coverage.
LKM808E standard base: A robust, industry-standard mold base that provides consistent alignment and structural stability during repeated molding cycles.
738H steel cavity: Pre-hardened to HRC32–36, offering excellent toughness, wear resistance, and polishability. It withstands the abrasion of TPU injection while maintaining precise cavity geometry.
Long service life: The steel’s uniform hardness prevents deformation, ensuring the mold retains its shape and surface finish over thousands of shots.
Smooth, burr-free surfaces: Eliminates sharp edges or rough spots, critical for child safety in soft toys.
Enhanced visual clarity: Creates a clean, uniform surface on the TPU layer, showcasing colors and designs vividly.
Easy demolding: The polished finish reduces friction, preventing the soft TPU part from sticking or tearing during ejection.
First shot (hard core): A rigid plastic core (PP/ABS) is injected into the mold, forming the structural base of the toy.
Second shot (TPU overmold): The core is repositioned, and TPU is injected over it, creating a soft, grippy, and tactile outer layer.
The design ensures strong adhesion between the core and TPU layer, preventing peeling or delamination with repeated use.
Optimized venting and cooling eliminate common TPU defects like bubbles, sink marks, or warpage, resulting in a safe, durable toy.
