Muto Vietnam's Molding Capabilities: Integrated Support from Mold Making to Molding, Secondary Processing, and Assembly
■ Strengths of Muto Vietnam's Molding Process
◆ Strength 1: Large-scale production system by a specialized molding team of 196 members
• Many specialized injection molding staff permanently stationed
• Stable production with 24-hour operational lines
• Capable of handling a wide range of products, from small precision parts to medium-sized exterior parts
→ A production system strong in high-mix, high-volume lots.
◆ Strength 2: Minimizing troubles through "in-factory collaboration" with the mold department
• Mold processing: 119 members
• Mold design: 13 members
Since both are located within the factory,
Mold adjustment → Molding trial → Improvement → Rework
can be executed "within the same day."
A speed absolutely unachievable by outsourced companies.
◆ Strength 3: Strong in molding exterior parts and precision parts
Muto Vietnam has extensive experience in the following:
• Camera parts
• Optical parts
• Automotive interior parts
• Exterior parts for home appliances
Required quality:
• Surface quality
• Gate processing
• Glossiness
• Suppression of warpage and distortion
Possesses know-how to achieve these at a high level.
◆ Strength 4: Molding that understands the conditions of secondary processing and assembly lines
In-house:
• Painting department
• Printing department
• Laser processing
• Assembly line
allows for setting conditions during the molding stage with the final process in mind.
Examples:
• Surface condition that prevents uneven painting
• Gate and dimensions that minimize printing position deviation
• Molding conditions that consider clearance during assembly
◆ Strength 5: Exquisite balance of Japanese quality × Overseas production
• Inheriting technology from the Japanese head office (Muto Seiko)
• Production management based on Japanese quality standards
• While optimizing costs through Vietnam production
◆ Strength 6: Reliability of global supply
Overseas shipment ratio is approximately 75%.
Capable of supplying to Japan, Thailand, Singapore, and Europe.
