The demand for high-quality, precise medical devices is rising. Yet, lead times often limit how quickly these devices reach the market. In this case study, an injection mould company faced long lead times, impacting its ability to deliver products on schedule. By partnering with a skilled mold maker, the company reduced lead times significantly. Through advanced injection molding techniques and improved injection molds, they met industry standards and market demands.
The Importance of Lead Time in Medical Device Tooling
For medical device manufacturers, short lead times are crucial. Medical devices must meet stringent quality standards, and delays can hinder patient care and product launches. Shorter lead times help manufacturers:
- Meet Market Demand: Rapid response to new needs.
- Maintain Quality Standards: Ensure reliable, high-quality products.
- Reduce Costs: Less time lost in production delays means lower costs.
However, tooling for medical devices requires precision. High standards for material selection, mold design, and part consistency make the tooling process complex.
Identifying Lead Time Challenges
The injection mould company struggled with long lead times for its medical device components. Key challenges included:
- Complex Tooling Requirements: Medical tooling requires tight tolerances.
- Frequent Mold Adjustments: Minor design changes delayed production.
- Material Limitations: Special medical-grade materials slowed down molding cycles.
These issues created bottlenecks, delaying production and increasing costs. The company decided to bring in a mold maker with expertise in medical device tooling.
Step 1: Collaborating with a Mold Maker to Identify Improvements
The mold maker began by examining the company’s current injection molds and tooling processes. They identified areas where faster lead times were achievable, without compromising quality. The mold maker focused on:
- Mold Design Efficiency: Improving mold designs to reduce cycle times.
- Material Optimization: Selecting materials suited for medical-grade applications.
- Automated Processes: Using automated processes to reduce human error.
This collaboration set a strong foundation for achieving the company’s lead time goals.
Step 2: Implementing Advanced Injection Molding Techniques
The mold maker recommended advanced injection molding techniques. These methods aimed to optimize each production stage, allowing the injection mould company to streamline processes and reduce delays.
Optimized Cooling Systems
An efficient cooling system is essential for fast production. With advanced cooling channels, the mold maker helped reduce cooling time, minimizing lead times without sacrificing part quality. Proper cooling also prevented defects, making the process more reliable.
Enhanced Injection Pressure Control
Medical device parts require precision. The mold maker introduced enhanced pressure control during the molding process. This adjustment allowed for more consistent fills, reducing errors and the need for rework.
Improved Cycle Times
Cycle times directly affect lead times. The mold maker analyzed cycle times and reduced them by using more efficient material flow and shorter cooling stages. This approach accelerated production without compromising the strict quality required in medical tooling.
Step 3: Designing Durable and Accurate Injection Molds
Durable injection molds are essential in high-volume production for medical devices. Molds that hold up to repeated use reduce downtime and maintenance needs, leading to shorter lead times. The mold maker focused on:
- High-Precision Design: Using CAD software for exact dimensions.
- Material Selection: Choosing mold materials that withstand high wear.
- Streamlined Ejection Systems: Ensuring parts ejected quickly and precisely.
These adjustments led to durable injection molds, minimizing the time spent on repairs or maintenance. The injection mould company saw immediate reductions in lead times as a result.
Step 4: Implementing Rapid Prototyping for Faster Design Approval
Prototyping often extends lead times. However, rapid prototyping can speed up the approval process by allowing faster feedback. The mold maker suggested using rapid prototyping to:
- Test Mold Designs Quickly: Prototypes allowed the team to identify and address design flaws early.
- Reduce Risk of Rework: Early testing helped avoid costly rework on final molds.
- Improve Communication: Rapid prototyping provided clear visuals for stakeholders, expediting design approval.
With rapid prototyping, the company achieved quicker design validation and approval, further reducing overall lead times.
Step 5: Implementing In-Line Quality Checks
In medical device manufacturing, quality cannot be compromised. However, thorough quality checks can add time to production. The mold maker introduced in-line quality checks that streamlined this process, allowing for faster and continuous monitoring:
- Automated Inspection Systems: Automated cameras checked parts as they came off the line.
- Dimensional Monitoring: Sensors measured part dimensions to ensure accuracy.
- Real-Time Feedback: Any quality issues detected were corrected immediately.
By integrating quality checks into the process, the injection mould company maintained high quality without slowing down production. This system eliminated the need for time-consuming post-production inspections.
Step 6: Training Teams for Efficient Mold Setup and Operation
Quick setup and efficient operation of injection molds are essential for maintaining lead times. The mold maker worked closely with the company’s engineering team to provide training on efficient mold setup techniques. The training focused on:
- Standardized Setup Procedures: Minimizing setup time by using standardized procedures.
- Machine Calibration: Ensuring machines were calibrated correctly for each part type.
- Problem-Solving Skills: Teaching operators to quickly resolve minor issues, preventing delays.
The trained team was able to set up and operate molds more quickly, helping the company meet lead time goals consistently.
Results: Significant Reduction in Lead Times
By implementing these strategies, the injection mould company achieved a noticeable reduction in lead times. Key outcomes included:
- Shorter Production Cycles: Optimized molds and reduced cooling times led to faster production cycles.
- Reduced Rework and Scrap: Enhanced precision reduced the need for rework and cut down on material waste.
- Efficient Approval Process: Rapid prototyping sped up design approvals, reducing overall lead time.
- Improved Production Quality: In-line quality checks ensured that parts met medical standards without added inspection time.
With these improvements, the company could better meet demand and deliver medical device components on schedule.
Lessons Learned for Other Injection Mould Companies
