Production Capabilities

Sodick Injection Molding Machines

The Sodick all-electric precision injection molding machine series includes 450T, 300T, 200T, and 100T models. With exceptional dynamic response and stable molding accuracy, it is capable of covering the full size range of products from miniature medical components to large equipment housings. Featuring closed-loop control systems and servo-driven technology, it achieves precise control over injection speed, pressure, and position, ensuring consistent molding and high repeatability—ideal for applications with tight tolerance requirements in the medical, electronics, and precision manufacturing industries. The entire machine is designed for cleanroom-compatible production and can be integrated with an MES system for full-process quality monitoring and data traceability, making it a core asset in smart manufacturing and high-end medical injection scenarios.

Extrusion

Kingsin Custom Medical-Grade Extrusion Machine is engineered for advanced medical and scientific applications. All critical contact surfaces are made from 316L medical-grade stainless steel, offering excellent corrosion resistance and enduring strong acidic or alkaline cleaning environments ranging from pH 1 to 14. The extruder delivers outstanding precision, capable of customizing tubing diameters as small as 0.22mm with a tolerance of ±0.01mm—ideal for organ-on-chip, microfluidic, and cell culture channels where dimensional stability and biocompatibility are critical. The system supports rapid mold switching for multi-spec production, making it suitable for both R&D-scale pilot runs and large-scale continuous manufacturing. It is a flagship solution advancing medical extrusion into the micro-nano domain.

SMT

The SMT (Surface Mount Technology) production line follows a precise and efficient sequence: mini board loader → IPM printer → 0.5m conveyor → CHM551 pick-and-place machine → 0.5m conveyor → Hongxiang HX-800AF-PC 8-zone single-track reflow oven → board unloader. This fully automated system provides high efficiency, precision, and consistency across the entire process—from board loading, printing, and component placement to reflow soldering and final unloading. Integrated with the MES system, it enables intelligent data tracking and quality control, making it particularly suitable for the mass production of high-density, high-reliability electronic products. Through optimized equipment configuration and layout, the SMT line reduces human intervention and errors, significantly enhancing a company’s manufacturing capability and delivery responsiveness.

Welding

Laser Welding

Our company utilizes advanced laser welding technology to deliver high-precision, low-heat-impact welding solutions for our clients. By using a focused laser beam, we achieve accurate and clean welds with minimal distortion, making this process ideal for applications requiring exceptional cleanliness, strength, and precision — such as medical devices and high-end industrial components. This technology ensures strong, consistent, and visually clean joints, providing a solid foundation for the quality and reliability of our precision manufacturing.

Ultrasonic Welding

Our company is equipped with efficient and stable ultrasonic welding systems to enable fast, clean, and reliable bonding of materials. This process uses high-frequency vibrations to fuse thermoplastics or certain metals without the need for adhesives or solvents — significantly improving welding speed while maintaining structural integrity and surface finish. Widely used in medical, electronics, and packaging industries, our ultrasonic welding process is strictly controlled to ensure that every product meets high standards of quality, precision, and consistency.

Assembly

Our assembly processes take place in an ISO Class 7 cleanroom, ensuring compliance with the strict cleanliness and reliability standards required for medical device manufacturing.

All personnel entering the cleanroom must wear protective garments, including coveralls, shoe covers, and face masks, to prevent particulate contamination.

Environmental Control：

Air Cleanliness: ≤352,000 particles/m³ (particle size ≥0.5μm), compliant with ISO 14644-1 Class 7 standard
Positive Pressure System: Maintains a pressure differential of 10–30 psi, automatically adjusted via differential pressure sensors to prevent external contamination
Temperature & Humidity Control: Cleanroom equipped with HVAC modules for stable environmental control; temperature maintained at 18–28°C, relative humidity at 45–65%

This precisely controlled cleanroom environment ensures a stable and traceable foundation for the assembly of environmentally sensitive medical products.
