Hyper products
At CPI we recognise that the specialised compressors
used in the LDPE (low-density polyethylene) industry
are highly evolved machines. CPI are responsive
to the needs of this area of operation, having considerable
experience in the design and manufacture of these
specialist products to a high standard of quality,
precision and with the use of appropriate materials
for hyper packings, guide bushes, poppets, cups
and plungers.
In conjunction with users, we have been successfully
involved in the development and installation of
specialised designs for many specific applications.
As part of these collaborations, we offer an option
to manufacture parts using customers’ own unique
designs and specific materials.

CPI operates a quality system throughout
its manufacturing plants which conforms
to ISO9000 (BS5750). This discipline is
rigorously applied to all hyper products
recognising the critical task which they
must perform in service.
To achieve this high standard of quality,
CPI undertakes certain minimum
procedures for all hyper products, including:
• Careful selection
of the best raw materials, with supplier
audits.
• Chemical and mechanical
certification of all raw materials with
full traceability Ultrasonic inspection
of all raw materials for internal defects,
where product applicable |
•
Appropriate heat treatments and stress relieving
to achieve specified tensile strength range
and freedom from residual stresses
• Careful finish
lapping to precise size and surface finish
tolerances
• Magnetic particle
inspection of the finished surfaces, where
product applicable
• Surface hardness
and finish inspection
• 100% dimensional
inspection
• Full inspection
report, including documentary certification
for all heat treatments and N.D.T. inspections |
