| Item | Specification |
|---|---|
| Mold Configuration | 1×2 balanced cavity design, producing 2 handles per cycle |
| Runner System | 2-point valve gate hot runner nozzle, precise sequential control |
| Molding Material | Grey PP (base structure) + soft-touch overmold material (e.g., TPE/TPR) |
| Cavity & Core Steel | S136 stainless steel, high polishability and corrosion resistance |
| Process Type | Two-shot overmolding / insert molding for luggage handles |
| Application | Hard-shell and soft-sided luggage, travel bags, and suitcases |
Identical part quality: Balanced filling eliminates dimensional variation, ensuring consistent ergonomics, grip texture, and structural strength between handles.
Double output: Produces two complete overmolded handles per cycle, significantly reducing unit cost and supporting mass production.
Stable process control: Symmetrical cavity design prevents warpage or uneven shrinkage, critical for the handle’s structural integrity.
Sequential filling control: Each cavity receives precise, timed melt delivery, eliminating flash or material bleed between the core and overmold layers.
Zero cold runner waste: The hot runner system reduces scrap and ensures consistent melt temperature, preventing material degradation during the overmolding process.
Reduced cycle time: The valve gates allow faster mold opening/closing, ideal for the two-step overmolding workflow.
Superior corrosion resistance: Prevents pitting or staining from moisture or additives, ensuring clean, contamination-free parts.
Excellent polishability: Accepts fine polishing and texture etching, perfect for creating the smooth PP core and textured soft-touch overmold surface.
Long service life: Withstands repeated injection cycles of both rigid PP and soft TPE/TPR materials, maintaining dimensional stability and surface finish.
First shot (PP core): The rigid grey PP structural handle core is injected into the mold, forming the base skeleton with attachment points for the luggage frame.
Second shot (soft-touch overmold): The core is repositioned (or retained in the mold), and a soft, grippy material (TPE/TPR) is injected over key contact areas, creating a comfortable, non-slip surface.
The mold design ensures perfect bonding between the PP core and overmold layer, preventing delamination or peeling under heavy loads.
Optimized venting and cooling eliminate common overmolding defects like bubbles, poor adhesion, or uneven texture.
Ergonomic grip design: The overmold layer is shaped to fit the hand, reducing fatigue during heavy lifting.
Structural strength: The PP core is engineered to withstand high pulling forces and repeated use, while the overmold layer absorbs impact and provides grip.
Durable surface finish: The S136 steel allows for both the smooth grey PP finish and textured overmold surface, ensuring the handle looks and performs like new for years.
