| Selecting the right screw for your application can be a
challenging and time consuming endeavor. The PS&E Design Team
makes it easy. Our Engineering and Design Teams have a combined
150+ years of hands-on experience in solving simple to complex molding
problems. Although every molding project has unique variables, chances
are that our engineers have solved similar issues in the past. Whether you are looking to speed up cycle times, increase melt
quality and consistency, achieve a more homogenous melt, or enhance
material quality by reducing over shearing or long residence times, PS&E
can provide a custom design screw to solve even the most difficult
problems.
Our Commitment
Nothing is more important than getting it right the first
time. That's why our Design Team will do whatever it takes to
custom design the best screw, barrel, or complete injection unit to
match your specific application. We take pride in the ability to make
any screw. Our experienced Design Team is dedicated to providing
exceptional design and technical support to keep your molding operations
running efficiently. When you need assistance, we're here to make
your job easier. Let us know your specific needs and we can custom
design a screw to fit your specific application. For quicker

Quality Craftsmanship
All PS&E custom design screws are manufactured from the
highest-quality materials to withstand the stringent demands your
operations require. Our screws represent the finest workmanship in the
industry. Each custom designed screw is precisely manufactured to
your specifications using the latest technology and quality inspected to
ensure optimum performance. We inspect every screw for accurate
gauging of all dimensions and evaluate the screw's appearance and
performance requirements by performing quality checks to verify:
- Material Composition
- Hardness Testing
- Mechanical Dimensions
- Straightness
- Welding
- Surface Finish
Production Capabilities
We can manufacture any screw from 1/2" (12mm) to
10" (254mm) ID up to 25' in length.
Our screws are available in a variety of tool steels to meet your
specific requirements.
