Natech Plastics specializes in medical assembly.
We are an ISO-certified, family-owned provider of engineering, custom injection molding, and contract manufacturing. Our clients bring demanding applications requiring medical assembly services and best served by expert engineers.
Your medical device assembly needs a reliable process that reduces cycle times and produces quality parts. Natech controls the complete process and ensures quality standards are met at each manufacturing and assembly stage.
We also specialize in partnering with medical device companies and innovative medical startups. We have an engineering team guiding clients from design through final assembly.
INJECTION MOLDING IN USA
We take pride in the workmanship of our medical assembly services. We produce all of our tools and production parts in the USA. To ensure timely delivery, we operate three shifts per day, five days per week, and work on weekends as needed.
In addition, our injection molding presses with servo-driven robotics allow for high-speed automation and precise medical assembly production.
Our clients trust us to be the experts in engineering and manufacturing. Specifically, our engineers have experience in mold qualifications for medical IQ/OQ/PQ, high volume automation in consumer packaging, and engineering-grade resins and ultra-polymers in electronics.
Moreover, we have developed hundreds of products and manufactured millions of parts annually for the medical industry. Our medical devices include point of care diagnostics, microfluidics, and pharmaceutical drug delivery applications. At Natech, we are committed to quality and innovation. We strive to meet the needs of our clients and deliver exceptional results.
CONSUMER PLASTIC MOLDED PRODUCTS
For the consumer market we specialize in the automated production of high-volume disposables, unit-dose packaging, caps and closures, and over-the counter diagnostics and drug delivery applications.
In the electronics market, we draw upon deep experience in comprehensive analysis and testing for evaluation and verification to design and build lighter, more durable electronics components.
A Project Engineer manages each development project requiring medical assembly services, monitoring and controlling deliverables, and providing regular status updates.


We installed an ISO Class 8 Cleanroom, which allows our engineers to adjust temperature, pressure, and humidity to ensure the best quality parts for our clients. Natech holds an ISO 13485 certification and is registered with the FDA as a medical device establishment.
We also support medical assembly projects using several techniques, including 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 costs than creating new molds for each feature variation. We construct SPI Class 103 and 104 molds from P20 steel and aluminum with hot runners and cold runners.
Additionally, the production molds for medical assembly projects include high cavitation SPI Class 101 and 102 molds constructed from hardened steel. We design cold runner, hot sprue, and hot runner molds 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 plans also ensure regular cleaning and review of each mold at predefined intervals based on setups and cycles for medical assembly projects. Mold inspections, general mold maintenance, major mold maintenance and preventative maintenance are standard operating procedures.

In summary, Natech offers mid to high-volume automated and semi-automated manufacturing of plastic components and assemblies. These include single-use, metered-dose, and multi-use disposables. We focus on drug delivery, consumer packaging, and diagnostics for economical, high-quality solutions.
Our medical assembly product finishing capabilities are also extensive. These include hot stamping, banding, pad printing, silk screening, flaw coating, conductive painting, cosmetic painting, metalizing, and plating.
Additionally, we have a range of assembly and joining capabilities. These include product filling, foil/heat sealing, ultrasonic welding, heat staking, mechanical assembly, pinning & UV/hot melt gluing, custom packaging/kitting, and pouching.
Based in several regions across the US, we provide medical assembly services to clients nationwide.
Overall, Natech delivers high-quality, cost-effective solutions for the medical industry and beyond.
