Natech Plastics specializes in tolerance stack.
We are an ISO-certified, family-owned provider of engineering, custom injection molding, and contract manufacturing. Our clients bring demanding applications requiring tolerance stack services and best served by expert engineers.
Injection Molding in USA
We take pride in the workmanship of our tolerance stack services. All Natech tools and production parts are made in the USA. We run three shifts per day, five days per week, and weekends are run on an as-needed basis.
All our injection molding presses are equipped with servo-driven robotics for high-speed automation.
Clients trust Natech to be the tolerance stack 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, some with tolerance stack, and manufactured millions of parts annually for the medical industry. Medical devices include point of care diagnostics, microfluidics, and pharmaceutical drug delivery applications.
Consumer Plastic Molded Products
For the consumer tolerance stack 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.
Tolerance Stack
In the electronics market, including tolerance stack, we draw upon deep experience in comprehensive analysis and testing for evaluation and verification to design and build lighter, more durable electronics components.
Each development project requiring tolerance stack services is managed by a Project Engineer who monitors and controls deliverables and provides regular status updates.
Natech’s projects that include tolerance stack services 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.
The production molds for tolerance stack projects include 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 plans for projects that include tolerance stack services ensure 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 tolerance stack 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.
Our tolerance stack product finishing capabilities include hot stamping, banding, pad printing, silk screening, flaw coating, conductive painting, cosmetic painting, metalizing, and plating.
Our tolerance stack assembly and joining capabilities include product filling, foil/heat sealing, ultrasonic welding, heat staking, mechanical assembly, pinning & UV/hot melt gluing, custom packaging/kitting, and pouching.
We provide tolerance stack services in New York, New Jersey, Connecticut, Pennsylvania, Florida, California, Illinois, Oregon, Maryland, Massachusetts, Colorado, and Michigan and other regions.
