ALLWIN MOULD is a leading manufacturer of custom two-shot (2K) overmolding solutions, specializing in high-performance plastic components for industrial, construction, and power tool applications. Our overmolded parts deliver unmatched durability, ergonomics, and production efficiency for global tool OEMs.

These are precision-engineered two-shot (2K) overmolded plastic components, purpose-built for rugged industrial tools (including laser levels, tape measures, and handheld measuring devices). Each part combines a rigid, impact-resistant engineering plastic core (for structural strength and mounting integrity) with a soft, shock-absorbent TPE/TPR overmold layer, creating a single, chemically bonded component that delivers superior drop protection, non-slip grip, and long-term reliability in harsh job-site environments.

• Dual Material Integration: Rigid structural core (PP, ABS, PA66+GF) + soft TPE/TPR overmold, with permanent chemical bonding to eliminate delamination
• Precision Mould Design: Rotating platen or shuttle table 2K mould systems, ensuring perfect alignment and consistent overmold thickness across complex geometries
• Rugged Industrial Design: Optimized for impact resistance, dust/water sealing, and ergonomic handling, meeting IP65/IP67 ingress protection standards

• Mould Base Standards: Compliant with LKM, HASCO, DME international standards for global interchangeability
• Premium Tool Steels: Cavity/core inserts manufactured with NAK80, S136(H), or H13 hardened steel, delivering 500,000–1,000,000+ shot lifespan
• Dual Hot Runner System: Independent hot runners for each material, ensuring uniform filling, zero waste, and consistent part quality
• Advanced Cooling: Conformal water cooling channels + beryllium bronze inserts, minimizing cycle time and preventing warpage in complex geometries

• Structural Core: High-strength engineering plastics for exceptional impact resistance and dimensional stability
• Overmold Layer: Soft TPE/TPR for superior shock absorption, non-slip grip, and temperature resistance (-40°C to 80°C)
• Compliance: Fully RoHS, REACH, and UL compliant, meeting global industrial tool safety and environmental standards

• Tight tolerance control (±0.01mm) for perfect tool assembly and sealing
• Rigorous adhesion, drop impact, and environmental testing to ensure performance under extreme conditions
• ISO 9001/14001 certified, with strict QC aligned with European/American industrial tool industry standards
