Product Description

Bimetallic Barrel
 
Centrifugal casting or rotocasting is a casting technique that is typically used to cast thin-walled cylinders. It is chiefly used to manufacture rotationally symmetric stock materials in standard sizes for further machining, rather than shaped parts tailored to a particular end-use.

Technical Parameters
Product Name : Bimetallic Barrel
Material: JYN3 + JYK Series Alloy
Suitable Machine: Injection / Extrusion / Blowing
Available Size: Φ < 500mm, L < 8,000mm
Process Method: Centrifugal Casting
Surface Hardness: 52-62 HRC
Surface Roughness: < Ra 0.8
Screw Straightness: < 0.02mm/m

Advantages
By casting and sintering high quality alloy powder on barrel inside surface with thickness1.5-2.0mm, screws can get higher performance in both wearing & corrosion resistant performance.

Application
General plastics & engineering plastics with below 70% glass fibre filling.

JYK Series Alloy
At this stage, we have JYK-1, JYK-2 and JYK-3 alloy types and treatments for wear fighting
 

TYPE	COMPONENTS	HARDNESS (HRC)	Abrasive RESISTANCE	Corrosion resistance	applications
JYK-1, C	Fe, Cr, Ni	56 - 60	x	x	Recycling & engineering plastics, reinforced additives less than 20%.
JYK-2, B	Ni, W, Cr	58 - 62	xx	xx	Moderate corrosive, reinforced additives less than 35%
JYK-3, D	Ni, W, Cr	60 - 64	xxx	xx	High abrasive and moderate corrosive plastics

Suitability: (x good) to (xxx excellent).

JYK-3, D	8	1.4	5	4	3.3	40	0.5	Bal	< 1.0

*Highest composition of tungsten carbide can go up to 45%, which enables the barrels have 5 times wear-resistance capability than normal bimetallic barrels and up to 60% glass fibre filling in general & engineering plastics materials.
