Model RJ Machine Base

An optional heater control box controls the die temperature of metal-die compression stations. Temperature control is not available with plastic-die compression stations..

The RJ’s controls are easy to understand and use. There are no electronics (except with the heating option). A toggle valve opens or closes the compression station. The closing is limited by either an adjustable stop screw or by a force balance against your product sample, adjustable via the pressure regulator / gauge.

Model RJ with Alpha-Crimp™ Station

Designed specifically for PTCA-sized balloon-expandable crimping, the Alpha-Crimp™ compression station introduces unprecedented geometric accuracy and near-zero die-to-die gaps. Extreme precision, very low friction, no die-to-die wear, high radial force capability, high durability.

Diameter Length Max Radial Force Die Material
0-8 mm 75 mm 2670 N Hardened Stainless Steel

Model RJ with Red Crimp™ Compression Station

For longer-length or higher-force crimping, the Red-Crimp mechanism brings Alpha-Crimp-like accuracy to larger sizes. Stainless steel dies are guided by extremely precise bearing balls, resulting in near-perfect geometrical accuracy. Very low friction, no die-to-die wear, near-zero die-die gaps, high radial force capability, high durability.
Diameter Length Max Radial Force Die Material
0-16 mm 310 mm 2670 N Hardened Stainless Steel

Model RJ with Large Twin-Cam™ Compression Station

For very large diameter crimping, the Large Twin-Cam compression station provides very low friction and wear, and the best process control available for the size range. Small gaps, no die-to-die wear, high durability

Diameter Length Max Radial Force Die Material
0-60 mm 124, 186, 248, 310 mm 1450 N Hardened Stainless Steel

Model RJ with J-Crimp™ Compression Station

Blockwise’s workhorse compression station for a decade, with hundreds in service. For medium-sized general-purpose crimping, the RJ with J-Crimp™ provides good force or diameter control and very small die-to-die gaps. No die-to-die wear, proven superior durability.

Diameter Length Max Radial Force Die Material
0-16 mm 62 or 124 mm 955 N Hardened Stainless Steel

Model RJ with ZeroG™ Compression Station

For very large diameter crimping, the Large Twin-Cam compression station provides very low friction and wear, and the best process control available for the size range. Small gaps, no die-to-die wear, high durability

Diameter Length Max Radial Force Die Material
0-60 mm 124, 186, 248, 310 mm 1450 N Hardened Stainless Steel
