Harvest Medical Corporation is an innovator of blood
conservation technology and supplies its SMART PRePTM system worldwide.
Designed to specifically produce platelet concentrate rapidly and
simply, this medical marvel required the help Hy-Ten Plastics to
bring this amazing product to market.
Situation:
The company needed product development and processing
support, to create a sustainable supply of product to its global
customers.
Challenges:
The material chosen for this product was challenging
to mold due to its extrusion formulation and poor welding characteristics.
The part and tooling design was critical to its long term success
and time was of the essence.
Solution:
Hy-Ten employed not only its innovative approach
to product development to further reduce unit cost but pushed the
processing envelope by customizing the injection molding screw to
maximize efficiency. To complete this development and manufacturing
exercise, Hy-Ten had to resolve challenging welding issues associated
with the material. This lead to an unconventional but successful
welding process capable of meeting the high standards of medical
products.
Belimo Case Study
Belimo Aircontrols (USA) Inc. (Danbury CT), a division
of The Belimo Group out of Hinwil Switzerland is a world leader
in HVAC technology. They produce top of the line valves and actuators
to support worldwide markets.
Situation:
Belimo uses a Tefzel disc to control the rate of flow through the
valve. The discs were coming in oval instead of round, creating
a high scrap rate and slow assembly time.
Challenges:
The resin selected is challenging to mold in
a concentric form. The cost of the part needs to remain low to ensure
the competitiveness of the product. The part design cannot be changed
due to the existing product in the field. The part design leaves
the product susceptible to differential shrinkage pulling it out
of its concentric form.
Solution:
Hy-Ten agreed to build an experimental tool
to confirm that the product could be molded in a concentric shape.
We were able to produce the discs in the shape required, and we
provided samples from a variety of cycle times to get the best cost
to concentricity ratio. The disc project has lead Belimo to award
additional new programs to Hy-Ten, including the full line of discs
for their most recent product releases.
“Hy-Ten accepted a challenge to do what many
other injection molders said could not be done. Their engineering
staff tested a number of different solutions and responded very
well to the challenges in the development process. Then their moldmakers
had tools done in record time. Hy-Ten has been an invaluable partner
in new product development and production.”
