Shenzhen Sunmy Hardware Co., Ltd. delivers high-precision, engineering-grade plastic injection molded automotive components designed to fulfill rigorous OEM and aftermarket standards. Utilizing advanced injection molding techniques, our products—ranging from intricate internal structural housings to robust exterior aerodynamic guards—exhibit superior structural integrity, dimensional stability, and flawless surface finishes. Every component is completely customizable to match your exact CAD drawings, ensuring seamless integration into your specific automotive assemblies.
Our injection molding workflow leverages state-of-the-art machinery and premium-grade mold bases to guarantee high efficiency and zero-defect output. We deploy high-tonnage precision injection machines alongside multi-cavity hot/cold runner configurations optimized for complex geometries. Key technical aspects include:
Expert handling of technical polymers (ABS, PP, PA6, PA66, Acrylic, etc.) to achieve targeted mechanical strengths, impact resistance, and thermal performance.
Utilizing high-durability mold steels such as S136, NAK80, and 718 to maximize tool life, prevent flash, and uphold strict dimensional tolerances.
Computer-monitored injection pressure, temperature profiles, and holding times prevent warpage, weld lines, and sink marks.

A: We require complete 3D design files in STEP, STP, or X_T formats. Supplementary 2D drawings in CAD or PDF specifying exact tolerances, material preferences, and surface finishing requirements are highly recommended.
A: Standard mold fabrication and initial T1 sample delivery typically take 25 to 35 calendar days, depending on the complexity of the component geometry and the multi-cavity arrangement.
A: Our production facility is certified under ISO9001:2015. We enforce strict quality checkpoints: raw material inspection, first-article inspection (FAI), in-process statistical controls, and comprehensive final dimensional and cosmetic audits before export packing.
A: We offer highly flexible production options. We support low-volume trial orders for engineering validation as well as continuous high-volume mass production runs. Please contact our sales engineers with your project specifics for tailored support.
A: We support a wide spectrum of surface finishing techniques including VDI/MT texturing, matte finish, high gloss polishing, specialized heat treatment, and custom painting to meet both cosmetic and environmental durability requirements.
A: Depending on production volume requirements, we utilize premium mold cores and bases including P20, 718, 738, NAK80, S136, 2738, and 2316 steel, guaranteeing 250,000 to 300,000+ shots lifespan.
