Consultation details
The client: A foundry manufacturer received a request to "manufacture reproductions of old-style railway frame parts."
Request details: To manufacture a replacement part equivalent to the original railway part.
★Problem: The requested quantity is 10 pieces. Casting is a mass-production method, but it would require large-scale production such as mold making. "Another method would be better, but we don't know how to do it," said the casting manufacturer, consulting Machikoko about manufacturing.
Proposal
It can be manufactured without the need for molds through sheet metal fabrication and welding.
• Manufacturing process: Can fabrication → Painting
Manufacturing Process ① Frame fabrication using sheet metal processing. Three parts are created using laser processing and cutting, and then welded together to form the frame.
Manufacturing process ② The molded frame is painted at the paint factory. Primer + topcoat (no putty)
- Completed
We will produce and deliver a small quantity of the same product as the original.
We received a request to manufacture identical (replica) railway parts. Since manufacturing methods requiring molds would be expensive, we produced a small quantity using moldless metal fabrication and welding, and then delivered the painted parts.
Material: Steel
・Quantity: 10 pieces
Production period: 10 days
