Selecting the right screw for your application can be a challenging and time consuming endeavor. The SFP 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, SFP 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.

Quality Craftsmanship
All Services for Plastics, Inc. 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) OD up to 25' in length.
Our screws are available in a variety of tool steels to meet your specific requirements.
