Since 1981, we’ve built
a reputation for performance.
Performance without limits.

    I have worked with Liberty Pattern for over 30 years while employed at 3 aerospace foundries.  As with all suppliers, we compare the value of product & services received to the cost.  Liberty Pattern ranks at the top of the list.  Most of the tooling purchased involves complex tooling for aluminum and magnesium aerospace castings, gaging for core assemblies and pre-machining fixtures.  In addition, Liberty models and constructs the gating and provides iron castings (chills) used in the assemblies.  As part of their initial quotation we receive a preliminary tool assembly design with helps us convince our customers that were the best supplier for them.  We spend a lot of time with their engineers on tool design and find that they have anticipated potential problems and offer realistic solutions. 
    Developing new aerospace castings can be a long and involved process.  A large part is meeting schedules.  Liberty Pattern has the technical capability, staff and commitment to meet promised deliveries.  We have experienced this time and time again.  Liberty Pattern meets their commitments and our expectations!

    — Paul Olson, Director of Engineering, Azusa, Cudahy & Pomona

    It must have been 1992 when Bill August called at our Foundry in Larbert, Scotland. We were one year in to our experiences with a brand new Hunter 10 machine and struggling desperately to find a quality pattern making outfit who understood the casting business and could price work competitively. That competency was to be found at Bill’s Liberty Pattern Company. 22 years on and a generation down the line at both companies, we still order 100% of our pattern requirement from Liberty Pattern.

    Gary, Mike, Leo, Linda, Steve, Carl and all the others – what a team! And it does not stop there - many new faces are appearing and the skills and enthusiasm are perpetuated in another generation of youngsters, both family and general employees.

    Best regards Gary and congratulations to you and your team. You have a remarkable company with a great ethos and record of excellence. Keep up the good work.

    — Andrew Drysdale, Drysdale Brothers (Larbert) Ltd., Managing Director

    Throughout my thirty-five year career in the casting field, I have yet to find a more capable pattern shop to support the foundry efforts. Liberty Pattern has always been state of the art, not only in the shop equipment they have available on the floor, but in their approach to actual pattern engineering and construction as well.

    Liberty Pattern is a very valuable tooling supplier to Fansteel Wellman Dynamics. Their response to help us has met or exceeded our customers’ expectations and requirements. This has benefited us greatly in the industry.

    — Bob Hundley, Fansteel Wellman Dynamics

    It has been my absolute pleasure to work with Liberty Pattern for well over 20 years in building new patterns, dies, fixtures and even on occasion short run machine samples. When thinking of Liberty a number of words come to mind like Integrity, Loyalty, Superior Quality and Accuracy. Liberty is also one that does not sit back and let the world come to them, they continually are active in looking at ways to improve products and speed to market utilizing new technology and supporting their customer goals no matter what the obstacle.  I would HIGHLY recommend Liberty Pattern to anyone looking for a high performance pattern shop as I look forward to many more years of working with them as well.

    In one word – Liberty Pattern is REALIABLE – you always know what you’re getting and when --- If you’re looking for state of the art tooling, look no further than New Liberty, Iowa -- home of Liberty Pattern Company. Chicago Magnesium Casting Co. has used Liberty for over 20 Years – to make some of the most complex aerospace tools in the world. One crazy thing they always do is deliver your pattern equipment in PERSON.  This personal touch just adds to the fact that you know the tooling you’re getting will make the perfect casting for YOUR customer.

    — Richard D. Burnett, President, Chicago Magnesium

    Custom-Pak has done business with Liberty Pattern for probably 25 years now. Helping us build blow molds. Gary August and his team have always done a super job with anything we have given them. We rely on Liberty Pattern and the skills they have for 5-axis work when we just don't have the time in our machines. They have also done a fair amount of 3 axis CNC work for us through the years. We ask how long it will take them to complete the task we request and they will get it done within that time frame. Gary August and Steve Slininger are very professional yet personable. I would recommend Liberty Pattern for any type of pattern work or machining knowing that it will get done on time.

    — Mike Grinnall, Custom-Pak, PDC Facilitator

    I have had the pleasure of working with Liberty Pattern over the course of the past 25 years or so. I think of them not only as a supplier of premium quality patterns and fixtures but also as my friends. The work that they do is with no doubt in my mind the best in the business. From customer service to custom machining they always meet or exceed expectations. Great work guys.

      Vision Statement

      Our vision is to be the global leader that provides quality pattern tooling, fixtures and machining services by empowering and equipping our employees to be the best in the industry.

      Mission Statement

      Liberty Pattern Co. is a “Full Service Patternmaking Company” which provides the foundry industry with quality products, on time deliveries and customer satisfaction at competitive prices. This is accomplished by providing quality patterns and customer service that is second to none.


        The Right Mix – It takes more than a warm body with good intentions to do the job for you. It takes more than advanced technology and a huge stock of on- site materials. Although we strategically set the stage for the best outcomes with the best technology, our people truly are Liberty Pattern’s top asset. We are staffed with dedicated specialists in each department throughout our shop. They are united in performing to your highest level of expectations.

        Each one offers the right mix of education and on-the-job experience. Liberty Pattern pursues talent that has been shaped by the industry. We maximize their potential by providing state of the art equipment in each department. We take extra steps to strengthen overall performance with two highly skilled administrators. They are the advance professionals who expedite your calls, assure work flow, monitor inventory, accounting and an in-house payroll system. When accuracy and short turnarounds are the order of the day you can count on Liberty Pattern.

        But the true test of any company is the loyalty and commitment of its people. With an impressive average of 13 years employment with Liberty Pattern, we deliver the right mix of talent, training and real-world experience to serve the pattern industry above all expectations.

        Better performance begins with the right credentials: experience, skill, and the relentless pursuit of perfection. With that work ethic and the best tools of the trade, it’s clear that we offer the right mix for your project. It’s expressed this way: Better Equipment + Better People = Better Performance. There’s no limit to what we can do for you.


          One Size Fits All – We have 38,000 sq. ft. to work with. But it’s more than size that allowed us to become a premiere pattern shop. The quality of our products demand ultra-productivity out of every square inch.

          When you fabricate everything from raw materials to the finished product, it’s important that you have the best equipment, the best people and synergistic, strong work ethic under that roof.

          Liberty Pattern is committed to one stop fabrication on every job drawing from materials in-house. That requires sustaining a well-equipped, technology-driven environment and stocking large supplies of raw materials to assure fast turnarounds. We do our homework to keep current on the most productive tools in the industry.
          We’re equipped for maximum performance on every level. Liberty Pattern brings vast experience to the table. We’re comfortable with a wide variety of pattern scenarios that allows us to be on the same page with you.

          It’s not by chance that our people have the expertise that measures up to the level of our equipment. As a matter of fact, it’s essential to assure The Best Performance.


            Raising A Thoroughbred – You could see our bloodlines were right from the very beginning. Liberty refused to accept second best performance from the minute we opened the doors in 1981. It was just a two-bay service station the day before. But from that July morning on up to our first customer in September, and from manual technology to the most sophisticated CNC equipment on the planet, Liberty Pattern Company was in the race to finish in the winner’s circle.

            That requires top quality work and on-time, or better yet early deliveries. With this dedicated work ethic, we grew from that little service station to a completely modern 38,000 sq. ft. facility under one roof. An impressive achievement.  When you do it for over 30 years, becomes championship level performance surpassing every expectation. The kind you expect from a true thoroughbred.

            July 1981 – Liberty Pattern Company was founded by Bill & Gelene August.
