How To Optimize Plastic Injection Tooling To Achieve Micrometer Level Medical Precision?

The quality of plastic injection tooling basically sets the maximum precision that can be achieved with injection molded plastic components.

JS Precision picks S136 steel, precision CNC machining, and mold flow analysis tech to decide with 0.01mm tolerance in the molds, to make sure that there is precision, at the same time, the molds stay alive longer and the costs to customers are less overall.

Mold Flow Analysis for Shrinkage and Warpage Prevention

During the plastic injection tooling design process, JS Precision uses Moldflow to imitate melt behavior under 120MPa pressure thereby changing the gate location, size, and number. This way shrinkage and warpage are avoided and the product dimensional accuracy is well kept.

To give an example, it is like drawing the water flow path beforehand and not letting water flow in dead ends or get stuck. So, water (melt) flows equally through every corner and there is no water build up (which is similar to product defects).

High Hardness Stainless Steel and Long Lasting Mold Maintenance

For our plastic injection tooling we pick S136 stainless steel with HRC 48-52. Not only is it corrosion resistant and wear resistant, but it is also able to endure millions of cycles. On top of that, a full mold maintenance system is available to customers to help them reduce their mold replacement costs.

How To Ensure Structural Strength And Sealing In The Face Of Complex Parts Injection Mold Challenges?

Medical components have been miniaturized and require higher strength. This has not only increased their design complexity but also the manufacturing aspects of the parts injection mold.

JS Precision innovatively solves the issue of filling and sealing through modern injection molding techniques and precision insert technology, which allows customers to reduce the product scrapand be more competitive in the market.

Thin wall Molding and Pressure Balancing

If a component's wall thickness is <0.5mm, JS Precision will utilize a 150-180MPa high pressure and a 50-80mm/s high speed injection molding.

Besides, injection molding parameters will be balanced with holding pressure and mold temperature for a uniformly filled melt, which is going to lead to the prevention of brittle and deformed parts, allowing the structural strength of component to be crystal clear.

Insert Molding Reliability Assessment

JS Precision makes the best use of the structure to parts injection mold design phase to double the bonding strength between the metal insert and the substrate. Tensile testing guarantees a joint strength of over 500N that keeps the insert from coming off and medical components remain safe.

When Is HDPE Injection Molding The Right Choice For Medical Devices?

HDPE has recently taken the forefront in medical packaging owing to its excellent chemical stability and extremely Low water absorption capacity. Among medical injection molding, HDPE injection molding represents one of the prime directions.

JS Precision, through its accurate shrinkage compensation and mold temperature control,solved the problem of its high shrinkage rate of 1.5%-3.0% thus not only fulfilling the consistent dimensions in mass production but also raising the cost effectiveness of customers' products.

Advantages of HDPE in Biocompatibility Applications

HDPE meets the ISO 10993 standard for biocompatibility. Being non toxic, non irritating, chemically resistant, and having good impact strength, it is the most common material in the manufacture of diagnostic and medical equipment as well as medical packaging.

JS Precision's medical grade HDPE which has been subjected to biocompatibility testing is ready for production use.

Controlling Dimensional Fluctuations in Highly Crystalline Materials

The high degree of crystallinity in HDPE is one of the reasons for its dimensional instability. JS Precision utilizes a 2-stage holding pressure curve:

The first stage is to hold the pressure at 100-120 MPa for 5-8 s, the second stage is to hold the pressure at 60-80 MPa for 3-5 s, the result leads to uniform crystallization and the deviation in dimensions can be controlled within 0.02 mm.

If you are unsure whether your product is suitable for HDPE injection molding, you can submit your product drawings, and JS Precision will provide you with a free material compatibility analysis and production cost calculation.

JS Precision Case Study: Development Of High Precision 16 Chamber Insulin Pump Shell

Little plastic injection product components as well as the plastic injection tooling used are very effective for medical device miniaturization. This case study of the development of a 16-cavity insulin pump housing fully showcases JS Precision's engineering skills in finding solutions to its clients' main difficulties.

Project Background:

A medical company in Europe was the client for developing a high precision insulin pump housing of PC/ABS material.

The features included a very tight dimensional tolerance of 0.02mm, the capability of passing a 1.5m full angle drop test, and the mass production scrap rate of 1%. This part will have a direct impact on device sealing performance and assembly precision.

Challenges Encountered:

• Multi cavity Imbalance: The pressure difference between the edge and center cavity of the 16-cavity mold was 15%, with dimensional changes >0.05mm. The scrap rate during the test production reached 8%, failing to meet the precision requirements.
• Internal Stress Cracking: The complicated housing design and residual stresses made the screw holes crack during the assembly which lead to the direct impact of the yield rate.
• Long Production Cycle: The existing method was very time consuming during cooling, and finally, a single product cycle of 28 seconds was recorded, which cannot be used for meeting the needs of mass production and also increasing the costs.

Solution:

1.Runner Optimization:

Working with Moldflow, JS Precision engineers mapped the melt balancing in the hot runner system of the channel justifying the secondary channel diameter (lifing to 0.02mm accuracy).

These efforts resulted in decreasing the pressure exposure difference between the outer and inner cavities to 1.8% and the firm realization of the fresh filling of the 16 cavities with the melted material and ultimately solving the problem of inconsistent size.

2.Scientific Injection Molding:

The pressure curve of the holding stage was two stage. After filling at 120MPa, pressure was reduced step by step. First stage of the holding pressure was 100MPa for 6 seconds and second stage was 70MPa for 4 seconds.

This way the molecular chains had enough time to become completely relaxed internally, 70% of the stress was eliminated and no visible cracking occurred at screws holes.

3.Conformal Cooling:

Getting 3D printed conformal cooling water channels, which were in line with the cavity by the virtue of the shells' structural characteristics exactly control the mold temperature fluctuations within ±1°C, significantly reducing cooling time as well as dimensional deviations caused by uneven cooling.

4.Precision Inspection:

A sampling inspection of each product batch through a CMM (Coordinate Measuring Machine) is carried out during production, injection molding parameters are adjusted in a timely manner to maintain stable product precision.

Final Results:

• Extremely Tight Tolerance: The 16 cavities' key dimensions were accurately kept within 0.015mm, which is much better than customer requirement of 0.02mm, and this also translated to major improvement of dimensional consistency.
• Tremendous Increase in Yield: Not only scrap rate dropped to 0.2% from 8%, but also the products passed drop tests, thus customer saved around $80,000 on scrap costs each year.
• Cost Reduction: The time needed to produce one unit was reduced from 28 seconds to 24 seconds, which means that the customer would save 15% of the total processing costs, about $120,000 per year.
• Long term Partnership: The results achieved were greatly appreciated by the client and they gave JS Precision the go-ahead for the project producing three new insulin pump parts.
