🏥 Introduction
In the Medical Device and Precision Engineering industries, dimensional stability and process cleanliness determine the final product’s safety and reliability. SIMA Technology, located in Nakhon Ratchasima and part of the Muramoto Group, provides a fully equipped precision metal stamping operation certified to ISO 13485 for medical-grade production.

⚠️ Common Issues in Precision Stamping
Many factories face inconsistent hole dimensions, spring-back deformation, or unstable Progressive die performance during mass production. These issues often increase reject rates and overall costs, typically caused by incorrect tonnage selection, unstable press settings, or machines not suitable for high-volume continuous runs.

🔧 Stamping Capability of SIMA
SIMA operates 61 stamping machines from 10–300 tons, including:
• Single Shot (10–200t): 21 units
• Progressive Press (25–300t): 24 units
• Robot Press Line: 3 lines, 16 units
 • 80t × 4
 • 150t × 6
 • 150t × 6

This capability supports thin-wall parts, deep-draw components, and low cycle-time production with stable robot handling.

🩺 Capability for Medical & Precision Components
The wide tonnage range allows SIMA to stamp small components as well as large chassis and frame structures while controlling material deformation. Key benefits include:
• Stable dimensional consistency across lots
• High uniformity even in multi-stage Progressive dies
• Suitable for thin-steel, high-hardness materials, and stainless steel

Supported parts:
• Chassis
• Holder / Bracket
• Eyelet (Deep Draw)
• Thin-frame structures

🔍 Quality Control under ISO 13485
To support Medical Device requirements, SIMA operates:
• CMM
• IM
• 2 dedicated cleaning machines

📌 Suitable Applications
• Medical metal parts requiring high cleanliness
• Precision stamping for Sensor Housings
• Small deep-draw eyelets
• Multi-hole chassis
• High-flatness frame components

⚙️ Comparison with General Stamping Factories
• Better for High-Mix + Tight-Tolerance production
• Robot Line reduces human error
• Cleaning + QC systems meet Medical grade
• 24 Progressive presses support continuous high-volume production

🤝 Trust (EEAT)
“According to Mr. Waranon, Expert Engineer at SIMA Technology, all stamping processes are controlled under ISO 13485 and verified using CMM and IM systems to ensure every part meets customer requirements.” [1][2]
