Let’s discuss how VMT Reduced CNC Machining of Automotive Parts- ABS Sensor Housing Scrap Rates by 75% and Costs by 18% in just Six Months
Electric Vehicle Platform Manufacturer
Automotive (EV Sector)
balancing strict quality demands for a high-volume critical part with an unsustainable cost structure.
Client Overview
This is a fast-growing new energy vehicle manufacturer dedicated to building the next-generation electric vehicle platform.
Their team is highly focused on intelligent driving and safety features, placing extremely high demands on component precision and consistency.
With production capacity rapidly increasing, they urgently need a reliable manufacturing partner to ensure that critical components maintain high precision, quality, and cost control during mass production.
THE CHALLENGE
For their next-generation electric vehicle platform, they faced significant resistance with a critical precision component—the ABS sensor housing. Their long-term supplier, while historically reliable, struggled to maintain consistent dimensional accuracy and surface finish in the high-volume production required.
This resulted in unacceptably high scrap rates on their assembly lines, directly impacting their production schedule and significantly increasing rework costs with the original CNC machining manufacturer. At the same time, the manufacturer’s rising unit prices eroded their profits, jeopardizing the cost efficiency of the entire project in the fiercely competitive electric vehicle parts market.
For this critical, high-volume component, they were caught between their quality requirements and an unsustainable cost structure.
To address the high scrap rates and rising costs of ABS sensor housings, they partnered with us, a CNC machining specialist with more than 15 years of experience in producing high-quality automotive components. We applied its expertise in precision machining and multi-supply chain integration, ensuring that every stage from raw material selection to final shipment was tightly controlled.
With advanced capabilities including 5-axis machining, Swiss centering, turning and milling combination processes, and prototyping, VMT created a tailored solution for this critical part. We also provided over 40 surface treatment options such as heat treatment, PVD, oxidation, polishing, and sandblasting. A comprehensive quality system with manual and automated inspections, along with a dedicated testing lab equipped with 2D and 3D projectors, guaranteed consistent accuracy and reliability.
This approach delivered immediate results. The production yield rate reached 98 percent, assembly line scrap was reduced by 75 percent, and overall component costs decreased by 18 percent within just six months. With VMT’s precision CNC machining, the customer regained efficiency, improved profitability, and strengthened their ability to compete in the fast-growing EV market.
VMT quickly analyzed the root causes of the dimensional and surface quality issues. Leveraging their multi-supply chain integration and strict process control, we developed a customized solution that combined:
5-axis machining, Swiss centering, turning-milling compound machining, prototyping, and precision lathe processing.
40+ customizable surface treatments including heat treatment, PVD, oxidation, polishing, and sandblasting.
Both manual and automated inspection systems, including first article inspection, in-process checks, and final shipment inspection — all archived and traceable for two years.
Dedicated lab equipped with 2D and 3D projectors and other high-precision instruments to guarantee every part meets specifications.
THE RESULTS
With VMT now producing the customer’s ABS sensor housing, the customer saw immediate and significant improvements. Their assembly line rejection rate for this part dropped by over 75% in the first quarter, virtually eliminating rework and associated production delays.
Furthermore, VMT’s competitive pricing and strict adherence to specifications reduced the total cost of this critical component by approximately 18% within the first six months. This partnership not only restored the customer’s production efficiency and profitability but also significantly increased their confidence in delivering a high-quality product to market on time and within budget.
