Custom Machining for Robotics Parts — From Core Parts to Enclosures

Solving "inadequate precision causing jams, poor material wear resistance, and difficulty in small-batch custom"

We Manufacture Parts to Exacting Standards

Unlike traditional industrial products, the operational accuracy and reliability of a robot directly depend on the quality of its core mechanical components, which are designed to meet the following key performance benchmarks:


Ultra-precision component mating: Clearance between kinematic joints and transmission systems must be maintained within 0.01 mm to prevent functional seizure or long-term errors.


Durability: Robots typically operate over 1,000 cycles, requiring components to withstand intense wear.


RT Manufacture serves as a component manufacturing supplier for the robotics sector, specializing in manufacturing workflows tailored for robotic applications. Leveraging advanced CNC machining and injection molding technologies, we offer comprehensive solutions—from prototyping to mass production—ensuring that each component meets the specific functional requirements of a robotic system.


CNC Machining: The "Precision Guarantee" for Core Moving Parts of Robots

The operating accuracy of the robot depends on the core parts processed by the CNC. We have achieved the following technological breakthroughs based on the characteristics of the robot:


1. Material-process matching: When machining industrial robot joints, we use 5-axis CNC simultaneous machining, ensuring the coaxiality of the inner hole and outer circle of joint bearing seats is ≤0.003mm, preventing radial runout during movement;


2. Wear resistance optimization: For high-frequency motion robot drive shafts, we use a special process to increase the surface hardness to above HV800, thereby extending the processing life of robot parts;


Injection Molding: The "Efficient Solution" for Lightweight, Mass-Produced Robot Parts

Robot enclosures, grippers, and protectors need to balance "lightweight," "low cost," and "mass delivery." Our injection molding process is optimized accordingly:


1. Robot-specific materials: For service robot enclosures, we use PC+ABS alloy (impact strength ≥60kJ/m²), which can withstand daily collisions without cracking; 


2. Precision and assembly adaptation: Using "In-Mold Decoration (IMD)" technology, we achieve "one-time molding + texture/logos" for robot enclosures, avoiding secondary printing peeling; 


3. Mass production capacity guarantee: Equipped with 8 injection molding machines (120–300 tons), we support "multi-cavity simultaneous production" of robot parts, and delivery lead times are 20% shorter than the industry average.


Our Advantages in Robotics Part Custom

1. Deep robotics industry adaptation: With over 6 years of experience in machining robotics parts, we’ve served more than 30 robot manufacturers. Familiar with industry standards(ISO 10218 for collaborative robot safety)), and we provide "part machining + working condition adaptation suggestions";


2. End-to-end quality control: Every batch of robot parts undergoes "coordinate measuring machine precision testing, We provide inspection reports before delivery, seamlessly integrating with robot Whole machine quality inspection process;


3. Flexible customization support: Seamlessly transitions from "small-batch R&D samples (minimum 10 units) to mass production (minimum 1,000 units)".

Providing Diversified Manufacturing Solutions for The Robotics Industry

We specialize in providing high-precision, high-quality manufacturing services for the robotics industry, equipped with a variety of advanced processing technologies to meet your diverse needs from prototype development to mass production.

CNC Machining

CNC Milling utilizes multi-axis CNC milling machines to precisely process complex-shaped automotive components such as engine blocks, transmission housings, and chassis parts. It is suitable for materials like aluminum alloy, steel, and cast iron, enabling high-precision and high-efficiency production. CNC Turning, on the other hand, focuses on machining rotary parts like camshafts, pistons, and bearing seats. Through high-precision internal and external cylindrical machining, threading, and end-face processing, it ensures dimensional accuracy and surface finish of the parts.

Sheet Metal Fabrication

We possess advanced sheet metal fabrication equipment and technology, capable of processing various metal sheets such as steel, aluminum, and stainless steel. We offer a full range of services including laser cutting, bending, stamping, and welding, producing automotive body parts, chassis components, interior trim parts, and more.

Injection Molding

We utilize state-of-the-art injection molding equipment and molds to produce complex-shaped plastic automotive components such as dashboards, bumpers, and interior trim parts. Using engineering plastic materials like ABS, PC, and PA, we ensure our products exhibit excellent strength, heat resistance, and corrosion resistance.

Silicone Molding

Silicone molding is a fast and cost-effective method for prototyping and small-batch production, ideal for manufacturing elastic automotive parts like seals, gaskets, and dust covers. Based on 3D models or physical samples provided by customers, we can quickly create silicone molds and conduct small-batch production, helping customers efficiently validate product designs and functionality.
