Selecting an Equipment Manufacturer

It is an important step in selecting an appropriate manufacturer of clean room equipment. Manufacturers should maintain high standards in all fabrication methods and processes. They should be specifically skilled in stainless steel fabrication. Much of the equipment in a clean room is from stainless for many reasons.

Stainless Steel Fabrication Advantages

1. Strength
2. Cleanability
3. Corrosion Resistance

1. Strength

Clean room equipment fabricated from stainless steel provides the highest industrial strength construction. It allows your equipment to withstand the daily abuse of personnel. Stainless equipment will give the greatest level of durability over other materials. Many components are now able to be welded instead of fastened. This ability further extends its industrial strength by minimizing bolted connections that requires maintenance and tightening over time.

2. Cleanability

Stainless steel is smooth and easy to clean. It’s chemical properties make it highly resistant to most cleaning solvents. Clean rooms with vial and syringe conveyors will face problems with broken glass. Constructing equipment of weaker materials may allow this broken glass to embed itself in the surface of the material. Stainless clean room equipment withstands such contact with broken glass. It’s rigid properties keep your equipment’s surface smooth and easy to clean

3. Corrosion Resistance

Stainless is resistant to corrosive chemicals and maintains much of it’s corrosion resistance even after being damaged, nicked, or gouged. Other materials require a protective layer to add any level of corrosion resistance. This added layer is easily removed once damaged even slightly. After this occurs the base material is susceptible to rusting and harboring of other contaminants. Stainless fabricated equipment removes this problem.

Manufacturing with Quality Assurance

Metal fabrication companies typically work with a wide range of materials and equipment. Rarely do they specialize in a particular material and industry. They often outsource and subcontract much of their fabrication process to outside companies. This provides greater capabilities for the original equipment manufacturer. However it introduces issues with the quality of the end product.

1. Cross Contamination
2. Specification Adherence

1. Cross Contamination

Manufacturing equipment made of regular steel can contaminate tools, dies, and fixtures that were used in the fabrication process. These items are often used on both regular steel and stainless steel products with no regard to maintaining the inherent corrosion resistant properties of stainless steel.

2. Specification Adherence

Lacking the control of an entire fabrication process can be a serious problem in quality. This is especially important when creating equipment for clean rooms. Such equipment requires an above industry standard of cleanliness and aseptic features. Specific requirements for surface roughness, polished welds, and passivation are just to name a few. A common requirement is to upgrade the material from 304 stainless to 316 stainless. However there are no visual differences between the two grades of stainless and can easily be mistaken for one another. Further material classifications and tracking must be in place to ensure the correct material is being used.

These are all common quality issues when outsourcing any of the fabrication process. A company simply cannot control, monitor, or ensure the quality of their product while outsourcing fabrication processes. Always search for a quality stainless steel manufacturer that meets the above mentioned requirements.
