3D Design Services

RENTAPEN INC. Specializes in Weld Fixture Design & Build. We can design and build a manual or robotic welding  fixture based on your needs. We can serve any industry — agricultural, recreational vehicle, furniture, or any industry requiring weld jigs.

If you want to hold your product parts in just the right place while they are manually or robotically welded, you have come to the right place!

Need Expertise?  Our Design Engineers have designed hundreds of large and small weld fixtures.  Our team includes a range of talent, education and experience.  Giving you speed and accuracy in your weld fixture design.  From an Engineer with a Masters Degree in Engineering and much experience in designing weld fixtures, to the high energy, high speed of a high-tech intern with a passion for all things mechanical.

Need Precision?  We design in adjustment shims as needed so that the weld fixture can be fine-tuned to your product standards before production begins.

Our weld fixture designs end up costing less to build because we integrate standardized, purchased components wherever it makes sense to do so.
