The production molds for PMMA molding 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.

For the consumer PMMA molding 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.

Our mold maintenance plans for projects that include PMMA molding 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.

Clients trust Natech to be the PMMA molding 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.

The size accuracy and precision of the crates are affected by the time of holding pressure before the melting material is frozen at the gate. The holding time of the crate depends on the material temperature, mould temperature, the size of the main flow channel and the gate. If the dimensions and process conditions of the main channel and gate are normal, then the pressure value with the smallest fluctuation range of the crate shrinkage rate shall prevail. The cooling time of the crate mainly depends on the thickness of the crate, the thermal properties and crystallization properties of the plastic, as well as a series of factors such as mould temperature. At the end of the cooling time, plastic crates should be guaranteed to meet the requirements, and then demoulding. If the cooling time is too long, it will not only reduce production efficiency, but also cause difficulty in demoulding complex parts, and even demoulding stress will be generated during forced demoulding. Other factors affecting the moulding cycle include whether the moulding process is continuous and automated.

Our PMMA molding 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.

How to make plastic crate? What is the plastic crate moulding process? What are the factors that influence the moulding cycle? The time required to complete an injection moulding process is called the cycle time, also known as the moulding cycle. The cycle time of plastic crate mould directly affects productivity.

In the electronics market, including PMMA molding, we draw upon deep experience in comprehensive analysis and testing for evaluation and verification to design and build lighter, more durable electronics components.

We provide PMMA molding services in New York, New Jersey, Connecticut, Pennsylvania, Florida, California, Illinois, Oregon, Maryland, Massachusetts, Colorado, and Michigan and other regions.

We are an ISO-certified, family-owned provider of engineering, custom injection molding, and contract manufacturing. Our clients bring demanding applications requiring PMMA molding services and best served by expert engineers.

We take pride in the workmanship of our PMMA molding 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.

Each development project requiring PMMA molding services is managed by a Project Engineer who monitors and controls deliverables and provides regular status updates.

Therefore, in the plastic crate moulding process, should be in the premise of ensuring high quality, to shorten the moulding cycle of each stage of time. In the whole moulding cycle, injection time and cooling time are the most important, they have a decisive impact on the quality. The filling time in injection time is directly inversely proportional to the filling rate, and the filling time in production is generally about 3-5 seconds. The pressure holding time in the injection time is the pressure time on the plastic in the mould cavity, which accounts for a large proportion in the whole injection time.

Our precision injection molding options include scientific molding, R&D molding, high-cavitation molding, micro molding, over molding, and insert molding.

Our PMMA molding product finishing capabilities include hot stamping, banding, pad printing, silk screening, flaw coating, conductive painting, cosmetic painting, metalizing, and plating.

Natech’s projects that include PMMA molding 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.

We have developed hundreds of products, some with PMMA molding, and manufactured millions of parts annually for the medical industry. Medical devices include point of care diagnostics, microfluidics, and pharmaceutical drug delivery applications.

Our mid to high-volume PMMA molding 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.
