Case Study: German Medical Device Company Accelerates Product Launch With The Help Of Chinese Precision Machining

Challenge

A German start-up medical company needs to produce 200 sets of new minimally invasive surgical instrument core handles (Ti6Al4V titanium alloy, requiring biocompatibility certification).

German local quotes offered high prices (more than $280 per unit), with an 8-week lead time, which was above the budget and development schedules, the parts had complex curved surfaces and very tight tolerances of 0.025mm, hence five axis machining and medical-grade quality control were needed.

Solution

The medical device company teamed up with JS Precision and we came up with a tailored solution targeting their major pain points:

1.Close DFM Collaboration:

JS Precision engineers proposed that some non-critical right-angle designs be replaced by more manufacturable rounded corners which facilitated the parts' machinability and the time of machining was reduced by 15%, while the functionality was preserved.

2.Process and Material Optimization:

In conformity with ISO 13485, Ti6Al4V titanium alloy blanks of domestic production are used, 5 axis machining center is coupled with medical-grade coolant, and after the use of the burr-free surface is ensured by high rigidity machining. Also, the surfaces pedal bio-compatibility requirements.

3.Parallel Process Management:

A project manager in the performing of different tasks concurrently (machining, polishing, cleaning, and aseptic packaging) has been appointed to coordinate these parts and thus to reduce the time of waiting between the transitions. Quality traceability is 100% compliant, including material traceability (MTR) allowance for each batch of materials.

Outcomes

The components perfectly satisfy the drawing requirements (tolerance 0.025mm), the unit cost is lowered to $155 (about a 45% reduction), and overall lead time is kept within 5 weeks, enabling the customer's product to get into clinical trials 3 weeks ahead of schedule.

During the following mass production, the order quantity escalated to 1000 sets, which led to a further unit cost drop to $130, thus greatly increasing the product's market competitiveness.
