Ash provided me with more than injection molding... I was happy that they could machine my parts and assemble them too...        Roger R.

When you need a full solution and not just a plastic part Ash is your solution for

Plastic Injection Molding , Machining, Assembly, Pad Printing and more...

Our extensive capabilities, in house tooling and experience with problem solving is not just words... it's reality... watch our video.

We can simply quote your part requirements and deliver a fantastic experience for the best cost... or we can dive in and find manufacturing efficiencies to save you money. Working with ASH as an injection molding supplier, you will have access to thermoplastic molding creativity and people who are not afraid to find manufacturing and design efficiencies for your injection molded parts. This means you are the hero as you combine processes to save secondaries, use a larger machine to get more parts per shot or even combine secondaries to get a complete solution.

Specializing in Medical Injection Molding

ASH INDUSTRIES is an ISO 9001:2015 certified medical injection molding company with an ISO class 7 clean room.

We provide every option you need for the proper manufacture of medical devices, surgical instruments, durable or disposable medical products.

Since 1991, we have been supplying medical devices and assemblies to some of the biggest names in the healthcare industry.

ASH offers a wide range of capacity and press sizes that are state of the art. With injection molding presses ranging from  25 tons to 650 tons tons, no medical injection molding project is too big or too small.


Most of our plastic injection molding presses are equipped with high-speed, 3-Axis Robots for automated parts handling and inspection. Depending upon the volume of your medical injection molding project, ASH is equipped with manual or fully automated assembly equipment. If your product requires assembly, decorating, mechanical fasteners or special packaging, ASH has a plastic solution for you.

SUPERMOLD - Production Tooling with a lifetime guarantee

From purchase order to first article in 3 weeks in most cases. Spend “prototype dollars” on production molds designed to take advantage of production efficiencies within ASH Industries. SuperMold™ reduces costs and lead times for custom injection molds to process thermoplastic, silicone, or MIM components.  


At the same cost to you as a prototype mold, SuperMold™ uses tool steel to provide a production mold that is guaranteed for as long as you need parts. Our full tool shop allows quick turnaround to put parts in your hand when you need them.



At ASH THERMOPLASTIC INJECTION MOLDING manufacturing group within ASH Industries, our list of projects span a wide gamut of industries and OEM projects. From medical surgical devices to structural components for laser light shows to overmolded electronic components, we can do it for you. We understand FDA or FAA requirements so you know that you are working with experience in injection molding and thermoplastic molding.


All of the project engineers you will work with have one thing in common,  they all seek solutions to production questions. Customers also benefit from ASH's implementation of JIT and TOC programs to limit inventories for production runs of ten million assemblies to a thousand custom parts.


Engineers at ASH Industries understand the complexities of beginning a new project and will work to ease that transition. We will ask a lot of questions and will help you with the tooling to make the best parts at the best price.


PROS OF INJECTION MOLDING: Every production process has it's pros and cons. Here are some of the advantages of thermoplastic injection molding:


Accuracy: Thermoplastic injection molded parts are able to be produced with pin-point accuracy, which is a major advantage over other prototyping processes like 3D printing.


Surface Finish: Thermoplastic injection molding can be executed with a variety of general and engineering-grade resins. The process is also able to create parts with pristine surface finishes, which makes the production process viable to create not only prototypes, but small and large production runs. Rough or pebble textured surface finishes can also be created with the production process.


Speed: Parts that are thermoplastic injection molded are typically turned around within days. If it's used for prototyping, this allows developers to make design changes quickly, thereby enabling it to go to market sooner. And if the process is being used for manufacturing, runs can be completed within days, so they're able to be on store shelves sooner. The longest part of the injection molding process is the time that needs to be spent creating the mold. However, molds can also be created to fine-tune prototypes and then used again for a manufacturing run.


Predictor of manufacturability: Thermoplastic injection molding can be utilized for prototyping purposes. Parts can be completed and turned around quickly with in days, with accuracy and surface finish quality. This makes the process a great predictor of manufacturability. Often times, developers will order several early prototyping runs on other technology, then use thermoplastic injection molding to validate product design prior to green-lighting the product for manufacturing. Since parts can be crafted in several different resins, developers will also experiment with surface finishes and materials to see what material they want to use.
