Products
Irregular Shape Drawing
Nihon Shinkan's irregular shape drawing technology enables us to produce products with complicated cross-sectional shapes without machining.
-
Outside/inside diameter products with uncut ends
(inside diameter tolerance 0.06)
Conventional technology
Extrusion/casting, machining, hard alumite, honing
* Expense of machining causes cost problems.
Nihon Shinkan technology
Extrusion, special drawing, hard alumite
Merits
1. Die cost 1/2 - 1/5 less than casting.
2. 30 - 40% lower machining cost.
3. Lower lead-time by merit of total production including everything up to surface treatment.
4. Use of flattened material enables handling of same shape with different lengths.
Applications
Cylinders with radiating fin
-
Shaft material for timing pulleys
Conventional technology
Round/square bar, machining (cutting, milling)
* High cost of machining
Nihon Shinkan technology
Extrusion, special drawing
Merits
Dramatically reduces cost of machining.
-
Uncut irregular shaped long drawn materials
Applications
Motor cases
Rollers for OA equipment
Pipes for tripod legs
Precise dimensions (scaled to the hundredth degree) can be guaranteed for both outside/inside diameters without machining.
Long lengths can also be manufactured.
-
Hexagonal hollow pipe
Conventional technology
Round/hexagonal bar, inside diameter machining technology
* High cost of machining
Nihon Shinkan technology
Extrusion, special drawing
Merits

Applications
Material for making nuts for heat exchangers (for air conditioner tube for automobile)
-
Rotary actuator
Conventional technology
Round/hexagonal bar, inside diameter machining technology
Applications
Material for making pneumatic equipment
Dimension precision of outside diameter is improved by drawing. Strong aluminum
-
Cylinder/motor cases
Long drawn material with irregular shaped outside diameter and outside diameter fins possible with precise inside diameter dimensions (scaled to the hundredth degree).
