Streamlined Design Process

Our 3D CAD software utilizes direct 3D modeling to streamline the design process. When creating in CAD, our skilled engineers start with your ideas. We then create a 3D CAD design that you can review, ensuring the end product works as specified. After you proof the 3D drawings, our expert designers use CAM software to control computerized machines to then develop detailed molds that match the design specs.

Enhanced Productivity

The use of our CAD/CAM software allows our engineers to increase efficiency, making them skilled at finishing your project on time and within budget. That means that your productivity won’t suffer.

Our Software Allows For

Automated machining and job input specifics, making production streamlined
More complex task development; meaning you have more options in designing your custom molds
Streamlined manufacturing and planning through dynamic geometric molding, making the turnaround on your job faster—without sacrificing quality

Dynamic Molding

Dynamic geometric molding also allows our engineers to identify materials necessary for manufacturing – creating a materials list and ultimately generating the code required to machine the visualized tool. And even when working with multiple data sources and late-stage changes, our 3D CAD/CAM mold making allows our customers to move seamlessly from visualization to production—all while assuring our customers are compliant with industry standards.

Mold Qualification

ESTERLE offers exacting in-house mold qualification and process validation – so that our customers are assured of consistent product performance before the equipment is assembled on their production floor and integrated with existing manufacturing systems.

We offer mold try-out, qualification, and part production using our own sixteen state of the art injection molding machines ranging from 90 to 2600 ton. For larger forged tooling and machining needs, we offer both large modern CNC and manual horizontal boring mills, as well as vertical machining centers.

Mold Part Production

At ESTERLE, we offer complete mold part production and supply chain management for our customers – from raw materials to fully assembled components to manufacturing systems specially designed to integrate with your production line. And we deliver the flexibility to handle large or small volume – even on stringent deadlines. We make injection molds for all plastic parts applications, including compression and structural foam molds.

Mold Prototyping

At ESTERLE Mold and Machine Co., Inc., we can help you bring your ideas to life. In fact, our on-site design engineers are available to work with your team — from design ideas and development to material evaluation to testing for manufacturing feasibility and in-depth assessment for compliance of regulatory standards.

Save Money With a Prototype

Our team of experts is happy to help you develop a mold prototype, because we know that it can save you a lot of money in developing a new product. It offers a fast, low cost tooling solution for producing parts for fit and function testing. You can also test the molding process by using the production material. Finding any problems or design flaws or process flaws early in the process is critical to saving time and money during development.

Compression Molds

Dimensional Accuracy

With the advancements in mold construction and mold material technologies, ESTERLE has leveraged its experience to produce compression molds with unheard of dimensional accuracy. Our capability to create and put into production complex compression molds requires repeatable accuracy. We are so certain that our combination of detailed mold making and reproducible dimensional accuracy will meet even the most demanding part requirements that you can test the molds for production functionality before they ever ship from our facility. Repeatable accuracy translates into quality parts.

Minimal Material Waste

Speeding production time ensures an economical mold. Improving dimensional accuracy ensures a quality mold. But ESTERLE takes this efficiency one step further. Our engineers work with the most advanced 3D CAD CAM applications to develop molds that minimize material waste. Reducing scrap loss without sacrificing fast cycle times or repeatable dimensional accuracy sets ESTERLE’s compression molds well above its competition. Minimal waste translates into considerable cost savings.

Structural Foam Molds

Structural foam molds provide structurally sound parts with minimum warpage at an up to 20% lighter weight than conventionally molded parts. As such, structural foam molds save both time and money. When you need larger and sturdier custom-molded thermoplastics, ESTERLE Mold and Machine Company has the technology and the capacity to manufacture your structural foam molds.


ESTERLE has a complete 3D CAD/CAM online system featuring Solidworks. We can accept most file formats, including STEP, X_T, DWG, DXF, IGES, or PARASOLID. By using only the latest software technology, we ensure effortless changes and trouble-free mold modifications. We offer mold qualification services as well. Our advanced processes allow you the time to test molds before they are shipped to ensure no downtime when the parts reach production. We stay on top of the latest processes for lean manufacturing to allow you to manage your costs for parts production and reduce cycle times without sacrificing parts with structural integrity, warping, or reduced weight.


Our systems are flexible enough to accommodate both high volume and short runs. Our facility features 90, 220, 300, 400, (2) 500, 610, 720, (2) 850, 950, 1000, 1500, 1760, and 2600-ton injection mold machines. We have three, five, 10, 15, and 25-ton overhead cranes plus internal handling equipment. In addition, with outside lifting help, our machine load capacity can be pushed to 80,000 lbs. We have the capacity to produce extremely large structural foam molds to meet the requirements of nearly any project.
