The plastics manufacturing industry is the third-largest in the United States, making it a significant player in the economy. With over 18,000 plastics facilities in the U.S., production processes for molding and plastics must be lean and productive. To aid in their processes, t-slot has long been a key player in the manufacturing of plastic. T-slot can be found throughout this industry in various solutions such as: 

  • CNC Machine framing
  • Repair workbenches
  • 3D Printing tables
  • Racks 

Whether it’s racks for polymer casting or machine guarding for rotational molding, t-slot is an integral material for the plastics industry.

Design for Manufacturing

The goal of DFM is to help your process be as optimal as possible, reduce costs and time to market, and produce products of good quality. T-slot and DFM go hand in hand when producing plastics because it helps to minimize tooling costs, provide quick cycle times, and make products to the engineer’s original specifications.

Benefits of T-slot


At Parco, we provide complete custom solutions regardless of the manufacturing process you are designing or already have in place. The great thing about t-slotted aluminum extrusion is that it is adaptable to fit right into an existing setup. 

So, if lines are being retooled or processes need to become leaner, we can help create solutions that will stand up to your needs and layout. 


T-slot’s durability and ability to withstand temperature changes make it an ideal material for all parts of the process. From enclosures for work in process to mobility racks for finished goods and frames used in stamp forming, t-slot can handle the rigors of plastics manufacturing.


Another benefit of utilizing t-slot in the plastics and molding industry is that it is OSHA-approved for horizontal injection and thermoforming machines. Plastics manufacturing equipment is not only complex but uses a variety of processes to create finished goods. 


In thermoplastics, heat is the main factor in the manufacturing process. Other hazards include moving machinery in the extrusion phase and knives in the trimming process. T-slot can be used to make fixed barriers at risk points to ensure operator protection. 

Our Industry Experience

We serve many industries, including plastics and molding. We understand the design and safety requirements for the different processes. Our CAD engineers are happy to take your plans and specifications and create your solutions. We can provide free consultation and design advice as we create your project. 

We also have a free design quoter where you can upload your idea and create your solution yourself. Once complete, it will supply you with a 3D model and a bill of materials. If you would like to learn more about the solutions, we can create and provide for the plastics and molding industry, give us a call at 1-800-817-0617 or email us at

  • This was the first time I tried Parco-inc. for one of my t-slot projects. It was easy to find what I needed and order on the website. I got the parts quickly and the quality was great, so I will be buying here from now on!
  • Really good quality aluminum i can feel the difference between it and other parts i ordered from china also the measurements was on point
  • I use ALOT of these little anchor faster, every month. My regular vendor was out of stock, and so I found Parco and ordered from them. The fasteners arrived quickly, we're high quality, and they even worked with me on a bulk discounted price. 10/10 in all areas!!
  • I am a small business and needed the t slot in a hurry. They processed my order, cut to size and shipped in less then 36 hours and 2 days before Christmas. Wonderful customer service. Thank you
  • Just awesome. Great customer service and response to questions, all cuts and pieces exactly like I ordered, extrusions seem like quality, fast shipping, and well packed to protect the items. I can't say enough about the quality and service. Will order again.
