While
the art of deep draw stamping may be our greatest strength,
product fulfillment also requires dependable
in-house support capabilities at Drawform. These include
our:
Tool Room Our engineering and tooling assembly departments
use the latest in 3-D CAD/CAM technology to design and
build more than 95 percent of ITW Drawform's production
tooling.
Prototype Department
Staffed by highly experienced toolmakers,
this expansive and advanced department allows quick turnaround
of production-intent prototype samples. A valuable service
few others can offer.
Metallurgical Lab
Unlike many metal-stamping companies,
ITW Drawform actually has its own metallurgical lab. Here
we perform corrosion testing; complete grain structure
and circle grid analysis; and tests concerning microhardness,
physical properties, microetching and light photomicrography.
We do in-house microhardness testing of both raw materials
and finished parts, as well as some destructive testing
and mechanical Rockwell hardness testing.
Inspection Laboratories
Our two comprehensive inspection
laboratories each contain a direct computer-controlled
coordinate measuring machine, optical comparator, profilometer
and contour scope. Duplicate equipment offers security
in the form of back-up in case of equipment failure.
Presses
Fully equipped with the most efficient, state-of-the-art
machinery available, ITW Drawform has over 40 presses with
capabilities from 60 to 500 tons, utilizing three distinct
press styles: |
| |
- ICOP (Individual Cam Operated Plunger Press), or eyelet
press -Excellent for smaller, detailed parts
- Die-set, or transfer press - Best for larger, symmetrical
pieces. Transfer fingers move parts from one stamping
or forming station to the next; hydraulic upper and lower
plates hold stations in place for accurate part forming
and quick die change.
- Progressive die press - Ideal for asymmetrical parts,
a progressive die uses a constraining material web to
transfer parts from station to station. Finished parts
are trimmed from the material web at the final station.
Hydraulic upper and lower plates hold stations in place
for accurate part forming and quick die changes.

Training
Our machinery
is operated by skilled experts, many who’ve
been specially trained internally to meet our high standards
of product excellence. We work with the local community
college to maintain an accredited, four-year apprenticeship
program that’s registered with the U.S. Department
of Labor. Additional programs are available for die setters,
tool room machinists and operators.
Secondary Operations
In-house secondary operations allow us to maximize quality,
control and accuracy for development, scheduling, production
and cost of each project. Our extensive secondary operations
include: aqueous cleaning in both barrel and ultrasonic
type systems, vibratory deburring, staking, weld assembly
and other light assembly operations. Should additional
resources be required, we turn to dependable, respected,
outside sources for subcontracting tasks like plating,
painting, electropolishing and heat treating. |
