Terra Universal - Critical Environment Modular Cleanrooms, Hoods, Laminar Flow Benches, Glove Boxes

Manufacturing Facilities

In order to ensure complete quality control over every stage of the manufacturing process, Terra Universal operates a ten-building, 100,000 square foot manufacturing and administrative complex that offers comprehensive fabrication capabilities:

CNC Metal Fabrication

Terra Universal's three metal shops house CNC (computer numerical control) equipment to perform the following precision metal operations:

* Metal punching	* Sheet metal breaking	* Sheet metal shearing
* Precision machining	* Plasma & water jet cutting	* TIG/MIG welding

In addition, Terra provides electropolishing to produce the smooth, nonparticulating stainless steel surfaces required in cleanroom applications.

CNC Plastic Fabrication

Terra Universal's plastics shop provides precision CNC routing, cutting, drilling, forming and solvent/thermal welding a variety of plastics, including hard and soft acrylic, PVC, polypropylene and polycarbonate.

Terra has extensive experience in fabrication of static-dissipative PVC, which features molecularly embedded dissipative layers that yield a surface resistivity in the dissipative range (between 10⁶ and 10⁸ ohms/cm²).

Polypropylene Fabrication
This specialty fab is devoted to CNC routing, cutting, milling, and drilling of polypropylene used in wet processing and cleaning stations. Thermal welding techniques ensure durable, leak-proof joints required in critical applications with acids and other hazardous process chemistries.

Laminate Sealing

As a major manufacturer of cleanroom benches and storage cabinets, Terra Universal maintains a laminate shop that expertly seals all edges of the electrically controlled surface polymers over the fibercore substrates, yielding work surfaces that will not slough or outgas.

Electrical/Electronics Assembly

Most of Terra's controllers incorporate microprocessor-based control boards, which are manufactured, assembled, and tested on-site. Wiring of electrical equipment conforms with local electrical codes, and the use of all-stainless steel chassis helps maintain cleanroom compatibility. Most systems are available with third-party certification.

Cleanroom Cleaning and Packaging

On demand, final cleaning and packaging is performed in Terra's on-site Class 10 cleanroom, to customers' specifications.

Engineering

All engineering and design work is performed on the latest CAD/CAM workstations, and Terra's state-of-the-art CNC (Computer Numerical Control) manufacturing equipment ensures the highest levels of precision and repeatability. In addition to providing strong customer support in all custom work, Terra's engineering department is committed to continuous improvement of existing product lines and to ongoing research and development of new solutions to the most current cleanroom manufacturing problems.

Quality Control

Terra is committed to the goal of complete customer satisfaction in every aspect of our operations. To reach that goal, Terra is implementing an ISO-9000 quality management system. This program includes a dedication to continuous product improvement, realized through

* increased use of CNC processes (to improve dimensional precision and consistency);

* a key inline quality inspection program;

* a Class 10 final cleaning and packaging area.
