OEM Power Tool Handle Plastic Injection Mould Injection Mould PP+TPE

• Part Name: Power Tool Split Handle Housing (Upper & Lower Shell)
• Application: Electric chain saw, handheld garden power tools, rechargeable power equipment
• Structure: Complex 3D curved grip, multiple screw boss columns, undercut features, integrated motor mounting cavity
• Surface requirement: Matte texture finish, anti-slip grain on handle area, two-color option (black base + red decorative line)
• Material recommendation: PP+GF, PA66+GF, ABS+GF (reinforced plastic for high impact resistance)

✅ Complex Structure Precision Mould Design Multiple internal screw posts, undercut & slide lifter mechanism design. Professional design to avoid deformation, sink marks and warpage on large curved housing. Balanced gating layout to ensure stable filling of long irregular plastic parts.

✅ Textured Surface Mould Cavity Cavity surface can be etched with customized anti-slip grain texture. Consistent texture appearance, meet ergonomic grip requirements for power tools. High polishing available for decorative two-color boundary.

✅ Optimized Cooling System Distributed conformal cooling channels covering handle area, boss positions and thick-wall sections. Effectively reduce cycle time and eliminate sink marks on thick screw columns.

✅ Optional Single-Color / Two-Color Injection Mould Solution

• Single-color mould: Standard two-plate / three-plate structure
• Two-color mould: Rotary type two-shot injection mould, realize black main body + red decorative line in one molding cycle, improve production efficiency and reduce secondary assembly

✅ High Toughness Mould Steel Selection

• Cavity & core: 718H / P20HH / S136H based on surface requirement
• Service life: 500,000 ~ 1,000,000 shots
• Suitable for continuous mass production of glass fiber reinforced engineering plastics

✅ Anti-Warpage & Stable Demoulding Design Multiple ejector pins distributed evenly on large housing surface to prevent deformation during ejection. Special draft angle design for complex curved profile.

• Cordless electric chain saw housing
• Garden pruning power tool handle shell
• Handheld electric drill / grinder grip housing
• Rechargeable power equipment structural plastic parts
