Some of the Nicest Extrusion Cross Heads

Their Extrusion Heads look like pieces of Art! Some of the nicest Extrusion Cross Heads I've used. Tight tolerances and beautiful surface finishes. If you want the best extrusion heads, look at Guill. When using Guill Cross Heads, I am able to get an extrusion line running with small diameter thin wall tubing and run it all day without it drifting out or tolerance. The only downside is their prices are a bit higher that competitors, but you get what you pay for.

Guill is great!

Our firm sourced Guill Tool & Engineering to purchase some extrusion tooling for assembly of our medical devices. Guill is a great resource for us with their wide selection of tooling products. We have a lot of custom parts that we need to form and their products are able to fulfill our needs perfectly. Their sales team does a great job guiding us to the products that would fit our assembly process and they tend to have very accurate quotes. The products are delivered quickly and we are able to do what we do best. Would recommend this vendor to anyone!

Great Products

My company contracts with Guill Tool & Engineering to purchase tolls used in our prototype labs for assembly of our consumer products.. Guill has a wide selection of tools that works for all of our needs. It's been great being able to have one source for our tool needs and Guill is that source. I have interacted with both their sales and customer service teams and they have been fantastic. Highly knowledgeable and willing to go the extra mile to make sure we are taken care of. We will continue to use Guill for our tool needs and I would recommend giving them a chance.

Medical tube

Guill supplies our R&D dept with medical tubing. they are able to produce parts exact to your specifications which produces a high sense of security that your products will work seamlessly into your machine. their tubing is multilayered and has multiple lumen design to control concentricity and wall thickness which leads to high quality products. their engineering team is able to make their concentricity adjustments fixed or adjustable. use order their 800 series crosshead in sets and are still using the ones we ordered from 2 years ago. their representatives are easy to get a hold of and their turnaround time has always been great. we have never had our products delivery past our delivery date.

My business has been going through Guill for years now. We have always ordered our heavy duty carts from them. They have always helped us order in bulk with ease! The customer service knows their product very well. They have helped us with a lot of custom work at fair pricing. There pricing is the best pricing we have seen in this field. We highly recommend them.

Solid overall

Guill Tool & Engineering is a a great 1 stop shop for heavy duty industrial machinery needs. We have purchased several stands and carts to place in our warehouse to help temporarily store heavy machinery components. Very easy to use and transportable. We plan to use these guys again in the future. A great company.

Extrusion parts

Our extrusion line uses Guill rotary heads for the extruder. It is well designs and very robust. Guill has good customer service but can be a bit pricey. You get what you pay for.
