Product Description

Classification processing strategy

The Sanluo Precision factory formulates corresponding strategies for different CNC machining medical parts. For structural components (such as shells and supports), high-speed milling is adopted. The cutting speed of aluminum alloy is 500 to 1000 m/min, resulting in good surface quality and high efficiency. For moving parts (such as shafts and gears), turning and grinding are used to ensure dimensional accuracy and surface roughness. The roundness is no more than 0.003 mm, and the Ra value is no more than 0.4 μm. For sealing components (such as O-ring grooves and sealing surfaces), precision boring is used to ensure sealing performance. The size tolerance is ±0.01 mm, and the surface roughness is Ra 0.8 μm. For optical components (such as lens seats and lens tubes), single-point diamond turning is used, with a surface roughness of Ra 0.02 μm, which is of optical grade.

Batch production management

Sanluo Precision has established a complete batch production management system, becoming a large-scale CNC machining medical parts processing factory. By adopting the lean production method, waste is reduced and delivery time is shortened. Unit manufacturing means completing all the processes of a type of part in one processing unit, thereby reducing transportation and waiting time. Implementing TPM comprehensive production maintenance enables the equipment's OEE (Overall Equipment Effectiveness) to exceed 85%. Using the kanban pull production method, production is carried out according to the customer's order cycle, and the inventory turnover rate is greater than 12 times per year. The first piece inspection confirms that the process parameters are correct, and process inspection is conducted twice per hour to control the dimensional stability. The final piece inspection verifies the quality of the batch products.

Supply Chain Collaborative Management

Sanluo Precision Company has established the supply chain collaborative management for CNC machining medical parts. And it collaborates through the VMI (Vendor Managed Inventory) method. The processing factory has provided professional customized CNC machining medical parts services for medical enterprises and medical consumables providers, and has also established a cooperative relationship.
