Customized Factory Precision Lost Wax Investment Casting Car Spare Parts

Vehicle accessories casting parts are high-performance components that elevate automotive functionality, safety, and aesthetics. Manufactured through advanced die casting and investment casting processes, these parts utilize lightweight yet durable alloys such as magnesium AZ91D and aluminum A356, combined with reinforced polymer composites. Engineered to meet stringent OEM specifications, they seamlessly integrate with vehicle systems while offering design flexibility for customization. From electrified powertrains to smart mobility solutions, these precision castings enhance vehicle performance, efficiency, and user experience across passenger, commercial, and specialty automotive segments.

Core Processing & Customization Services

Key Manufacturing Processes

Zeren specializes in silica sol investment casting and CNC machining as the core processes for VEA012 car spare parts. The process starts with high-precision mold production, followed by lost wax casting to form the initial shape of stainless steel and alloy components. We further conduct comprehensive post-processing, including annealing, hardening, and carburizing heat treatment, as well as black oxide, mirror polish, and anti-pollution flashover coating surface treatment. These steps ensure the parts meet strict automotive industry standards. The machining stage covers turning, milling, drilling, and threading, achieving precise dimensional control for each component.

Tailored Customization Solutions

We provide OEM one-stop investment casting services tailored to diverse automotive client needs. Supported by professional design software such as Pro-E, UG, and Solidworks, we accept multiple file formats including IGS, STP, and PDF for custom designs. Our customization covers material selection from austenitic stainless steel (304, 316L) to carbon steel (1045, 1050), and weight ranges from 1g to 30kg. We can also adjust casting radius, blind hole depth, and other parameters to meet the specific requirements of different vehicle systems.

Core Advantages & Application Scenarios

Competitive Advantages

Weight Optimization: Hollow-structured automotive investment casting parts reduce weight by 30-40% compared to traditional steel components, effectively improving fuel efficiency and EV range without compromising structural strength.

Corrosion Resistance: Multi-stage surface treatments provide excellent protection against harsh environments such as road salt and rain, extending the service life of parts.

Integrated Functionality: The integration of mounting points and wire routing channels into a single casting piece reduces assembly complexity and potential failure points, lowering overall production costs for clients.

Diverse Application Scenarios

EV Charging Ports: We produce robust, weatherproof housings with integrated cooling channels, ensuring thermal management and EMI shielding for fast-charging systems.

ADAS Precision Mounts: Our high-precision castings serve as stable mounts for LiDAR, radar, and camera sensors, providing reliable vibration damping and alignment accuracy.

Premium Exterior Trim: Lightweight and impact-resistant grilles, emblems, and spoilers with customizable finishes help automotive brands achieve unique visual differentiation.

Quality Assurance

Certified Quality Management System

Our products are certified by ISO9001:2015 and SGS, complying with international industry standards such as ASTM, DIN, and JIS. The entire production process follows strict quality control procedures, from raw material inspection to finished product testing.

Rigorous Technical Specifications

We maintain tight casting tolerance at CT4-CT7 (per GBT6414-1999 and VDG Merkblad P690 standards) and surface roughness at Ra1.6-Ra6.3. The minimum casting thickness reaches 2mm, with 1mm achievable in micro-regions. These strict parameters ensure that every lost wax casting car spare part meets the high-precision requirements of the automotive industry.
