In high-end equipment, aerospace, medical devices and other industries, the manufacturing capability of precision components directly determines the core performance of products.
Zorapid is deeply engaged in precision manufacturing. Supported by a flexible production system, micron-level precision control, and full-process quality management, we break the batch limitations of traditional manufacturing.
We support one-piece prototype development and also undertake mass production at the ten-thousand-piece scale.
We specialize in overcoming high-difficulty, complex, ultra-precision bottleneck parts — what others cannot manufacture, we deliver with professional expertise.
Core Technologies in Precision Manufacturing: All-Dimensional Breakthroughs from Process to Precision
Flexible Production Architecture: Seamless Connection Between Low-Volume and Mass Production
Traditional manufacturing faces the pain point of low volume being uneconomical and high volume being unachievable. Zorapid has built a flexible production system featuring multi-equipment cluster + digital scheduling + modular tooling, which completely solves the problem of batch adaptation.
Equipment Configuration: We integrate 3-axis/4-axis/5-axis CNC machining centers, Swiss-type lathes, slow-feed wire EDM, laser cutting, and SLM metal 3D printing equipment, covering the full production range from 1 piece to 100,000 pieces. High-precision standalone machines are used for rapid prototyping in small batches, while automated production lines are activated for linked mass production, with flexibly adjustable capacity.
Standardized Processes: We have established a proprietary process database. For more than 20 materials including aluminum alloy, titanium alloy, stainless steel, and nickel-based alloy (Inconel 718), we solidify parameters such as cutting speed, feed rate, and spindle speed. Parameters from small-batch prototyping can be directly reused in mass production, with a batch consistency error ≤ 0.01 mm.
Modular Tooling: The combination of universal fixtures and dedicated positioning modules reduces production changeover time to within 30 minutes. Compared with traditional dedicated tooling, small-batch production costs are reduced by 40% and mass production efficiency is increased by 50%.
Micron‑Level Precision Control: Breaking Technical Barriers for High‑Difficulty Components
Precision components are defined by accuracy. Zorapid focuses on solving manufacturing challenges for parts with complex structures, ultra‑thin walls, tight tolerances, and difficult‑to‑machine materials, delivering on the promise: What others cannot make, we can; what others make poorly, we make perfectly.
Precision Standards:
- Standard parts: Tolerance controlled at ±0.02 mm
- Critical precision parts: Tolerance up to ±0.005 mm
- Surface roughness: Ra ≤ 0.8 μm
- Fully compliant with industry certifications including ISO 13485 and AS9102
Breakthroughs in High-Difficulty Processes
Ultra-thin Wall MachiningFor parts with wall thickness ranging from 0.1mm to 0.5mm, we adopt low-speed high-rigidity cutting + constant-temperature machining to control thermal deformation and effectively avoid structural collapse and dimensional distortion.
Complex Cavity / Deep Hole MachiningAdopting 5-axis simultaneous machining technology to complete multi-surface processing in a single clamping. High-frequency vibration chip removal technology is applied to deep hole machining, solving common issues such as hole position deviation and excessive surface roughness.
Difficult-to-Machine Material MachiningFor high-hardness materials including titanium alloy and nickel-based superalloy, we use special coated cutting tools together with a high-pressure cooling system to reduce tool wear, improve machining stability, and resolve the industry pain points of difficult processing and high rejection rates.
Environmental and Equipment Assurance
The production workshop maintains a constant temperature of 22℃±0.5℃, constant humidity and anti-vibration conditions. All equipment is calibrated regularly: spindle precision is inspected daily, and CMM coordinate measuring machines complete annual certification. This eliminates precision errors caused by thermal deformation and equipment drift at the source.
Full-Process Quality Control: Zero-Defect Assurance from Raw Material to Shipment
Quality is the lifeline of precision manufacturing. Zorapid has established a closed-loop quality system of Three-Inspection System + Digital Traceability + Full-Dimension Inspection, ensuring no non-conforming products are delivered.
Incoming Quality Control (IQC): Before raw materials are put into storage, we verify material certificates, hardness and surface quality to prevent inferior raw materials from entering production.
In-Process Quality Control (IPQC): Full-dimensional inspection of the first article with 100% verification against 2D/3D drawings. Key dimensions are sampled every hour during production, supported by SPC statistical process monitoring to provide early warning of dimensional drift.
Final Quality Control (FQC): Full-dimensional inspection is conducted using Coordinate Measuring Machines (CMM), vision measuring instruments, roughness testers and other precision equipment. Inspection reports are issued, and products are only shipped after 100% compliance is confirmed.
Digital Traceability: Each batch of parts is assigned a unique QR code that records raw material batch information, processing equipment, operator data and inspection results. The entire production process is fully traceable, enabling rapid identification of the root cause of any quality issue.
