How To Choose The Right Deep Draw Stamping Service For Medical Grade Stainless Steel?

Medical-grade deep drawn stainless steel components need to be extremely precise, have a high quality surface finish, and be very consistent among other demands. Selecting the most appropriate deep drawing service is the key factor whether the item fulfills the specifications of the industry or not. LS Manufacturing, turning medical device manufacturing for several years, gives the buyers a correct choice.

Matching Methods for LDR and Material Drawing Ratio

Medical-grade deep drawn stainless steel parts usually necessitate complicated depth-to-diameter ratio (LDR) designs. The incorrect drawing ratio could easily cause the parts to crack and have very uneven wall thickness. Utilizing the 316L type material properties, we will accurately match the depth-to-diameter ratio and drawing ratio. This way, the stress is released and work hardening is prevented through multi-pass progressive forming while the rate of wall thickness reduction is controlled to within 10%.

Zero-Tolerance Control Solution for Micron-Level Surface Defects

Dental component surface defects are the major reason why the sterility and safety are being compromised. As high as 99.99% accuracy, our 100% visual inspection system with 360 coverage is very effective at detecting surface scratches as small as 0.01mm.

Inspection Items	Inspection Accuracy	Inspection Efficiency	Acceptance Standard	Industry Average
Surface Scratches	0.01mm	120 pieces/minute	No visible scratches	0.03mm
Wall Thickness Deviation	±0.005mm	100 pieces/minute	Deviation ≤5%	±0.01mm
Surface Roughness	0.01μm	80 pieces/minute	Ra≤0.3μm	Ra≤0.8μm
Dimensional Accuracy	±0.008mm	110 pieces/minute	Complies with ISO 13485 standard	±0.015mm

We select high-quality medical grade 316L stainless steel and intimately cooperate with professional deep draw stamping suppliers, by which approach we can trace every step of the production process from raw materials to finished products and reassure buyers completely.

What Factors Influence The Pricing Of a Custom Deep Draw Stamping Service?

When customers ask about custom deep draw stamping service, it often happens that they are puzzled by different sets of prices. Fundamentally, the price is dependent on several hidden aspects apart from the processing fee only. LS Manufacturing elucidates how these aspects have an impact on the price enabling purchasing and finance managers to have a clear understanding of their budget.

Analysis of Key Cost Driving Elements

1. Efficient Use of Raw Material: We have turned up the utilization percentage from the industry average of 65% to 85% by changing the layout. So roughly saving $3,000 on raw material for each batch of 5,000 pieces.
2. Mold Material Life: Carbide molds can be used to make over 1 million pieces, whereas D2 steel molds produce about 500,000 pieces. The former option, albeit a bigger initial cost, is more cost-effective over time for high-volume production.
3. Additional Processing Needs: Ultrasonic cleaning and deburring would range from $0.1 to $0.3 per piece, electroplating from $0.5 to $1.2 per piece, and vacuum heat treatment from $1.5 to $2.5 per piece.

Minimum Order Quantity (MOQ) Cost Decision Criteria

In order to get the lowest cost per unit, the production method should be selected based on the batch size.

• For MOQs less than 1,000 pieces, spinning or CNC machining is the most cost effective.
• Between 1,000 and 10,000 pieces, a simple mold deep drawing process can be introduced to meet the demand of a small batch or "trial production" of custom deep draw stamping services.
• When the order quantity is above 10,000 pieces, the cost effectiveness of deep drawing is clearly seen, as the unit price for bigger batches is lower.

How Does Deep Draw Metal Stamping Service Handle High-Strength Alloy Materials?

High-strength metals such as aerospace-grade titanium alloys and nickel-based alloys are very difficult to form. Issues like tearing, springback, and dimensional instability often occur. So, deep draw metal stamping service technology has very high requirements. We create customized solutions by combining test data and hands-on experience.

Core Metal Forming Technology Breakthrough

To carry out a successful deep draw metal stamping service, these two core technologies are utilized:

• Active heating technology allows lowering the hardness of the material and at the same time, tearing is minimized.
• Individually prepared extreme pressure lubricant will form a lubricating film, which reduces friction and prevents scratching.

Accurate Control: Coordinate Measuring Machine (CMM) Feedback Compensation in Real-time

• Real-time measurement: A coordinate measuring machine (CMM) makes real-time measurements of part dimensions and identifies deviations very accurately.
• Data feedback: The detection results are sent to the mold control system, which generates data support for compensation.
• Automatic compensation: The mold compensation value is adjusted automatically by the system, making sure that the parts' precision formed by the deep draw metal stamping process is consistently stable within 0.05mm precision.

The deep draw metal stamping technology that we employ was used for the mass production of precision parts of aerospace applications, over 1 million of units produced at a 99.98% passing rate, earning the recognition of the clients worldwide.
