We are an ISO-certified, family-owned medical plastics contract manufacturer who provides engineering, custom injection molding, and contract manufacturing services. Our clients bring demanding applications best served by our team of experts.
Contract manufacturing is the next step to bringing your product from design to reality. Beyond designing and injection molding, our additional services will optimize your product and help create finished devices.
Part Decoration
Natech’s mechanical and automated part decorating services enhance product appearance. Decoration can enhance part appearance and part performance. Natech customizes your product specific to your needs through our various finishing capabilities, including:
- Hot Stamping
- Banding
- Labeling
- Pad Printing
- Silk Screening
- Laser Marking
- Flaw coating
- Conductive painting
- Cosmetic painting
- Metalizing
- Plating



Product Assembly
Custom products require custom assembly solutions. When it is time to assemble your product, Natech’s engineering team designs a custom assembly process for your part.



Our assembly and joining capabilities include foil and heat sealing, ultrasonic welding, heat staking, mechanical assembly, pinning & UV/hot melt gluing, custom packaging and kitting, and pouching.
Filling and Sealing
After injection molding, many IVD products require filling and sealing with various liquids and reagents. Natech’s team of engineers develop customized solutions for low- and high-volume production.



Automated Processes
Natech’s automation engineering team is focused on creating automated solutions for our manufacturing, inspection, and assembly processes. Our team works with you to develop a scale-up plan for your projects, so you can transition from a semi-automated to a fully automated process.



Medical Injection Molding
We take pride in being the leading medical plastics contract manufacturer. All Natech tools and production parts are made in the USA. All our injection molding presses are equipped with servo-driven robotics for high-speed automation.
Our clients trust us to be the experts in engineering and manufacturing. Our engineers’ experience includes mold qualifications in medical IQ/OQ/PQ, high volume automation in consumer packaging, and engineering-grade resins and ultra-polymers in electronics.
We have developed hundreds of products and manufacture millions of parts annually for the medical industry. Medical devices include point of care diagnostics, microfluidics, and pharmaceutical drug delivery applications.
Consumable Products
Our product development projects are managed by a Project Engineer who monitors and controls deliverables and provides regular status updates.
Being the industry-leading medical plastics contract manufacturer, Natech’s development projects are supported by MoldFlow Analysis, a Viscosity Curve, a Cavity Balance Study, a Pressure Window Characterization, a Gate Seal Time Study, and a Cooling Time Study. Natech engineers are masters of insert configuration and design single-cavity R&D molds with steel inserted areas. Interchangeable plates, inserts, and sub-inserts allow for more rapid design iterations at lower cost than creating new molds for each feature variation. SPI Class 103 and 104 molds are constructed from P20 steel and aluminum with hot runners and cold runners.
Production molds are high-cavitation SPI Class 101 and 102 molds constructed from hardened steel. Cold, runner, hot sprue, and hot runner molds are designed with up to 128 cavities.
Precision Plastic Injection Molding
Our precision injection molding options include scientific molding, R&D molding, high-cavitation molding, micro molding, over molding, and insert molding.
Our mold maintenance plan ensures each mold undergoes regular cleaning and review at predefined intervals based upon the number of setups and cycles. Mold inspections, general mold maintenance, major mold maintenance and preventative maintenance are standard operating procedures.
Our mid to high-volume automated and semi-automated manufacturing of plastic injection-molded components and assemblies for single-use, metered-dose, and multi-use disposables for the drug delivery, consumer packaging, and diagnostics industries offer high quality at economical value.
Being the premier medical plastics contract manufacturer, we services New York, New Jersey, Connecticut, Pennsylvania, Florida, California, Illinois, Oregon, Maryland, Massachusetts, Colorado, and Michigan and other regions.
