B&H Tool Company, a world leader in extrusion tooling
technology, has introduced the industry's lowest volume microcrosshead. The BH25A
MicroCrosshead with Spiral Deflector delivers breakthrough microextrusion
performance for applications including microbore tubing, fiber optics, and
insulated fine wire. It was tested by major medical device manufacturers that
documented major improvements in process capability and stability.
The BH25A can extrude PEEK tubing with a product ID of .010”
and OD of .015". It will extrude FEP insulated fine wire with an OD of
.00471" and core OD of .00157". Tolerances are heavily dependent on
the process and material, but are generally in the range of +.0005".
Customers who tested the BH25A MicroCrosshead with Spiral
Deflector achieved exceptional ID/OD control, superior melt flow, highly
uniform material distribution, and short residence time. This resulted in
extraordinary concentricity and finished surface quality. Customers using this
innovative tooling say these features provide a significant competitive
advantage.
The BH25A is manufactured in two versions, both appropriate
for biomedical and other FDA applications. A 420 stainless steel model provides
optimum performance for thermoplastics, and a Hastelloy head is specified for
use with fluoropolymers.
