Custom Masking

Masking may well be the single-most unappreciated aspect of finishing. At best, many shop managers perceive masking as a necessary evil, something that must be done before the “real work” can begin. At its worst, it can be a frustrating and time-consuming nightmare. And while the introduction of robotics, process controls and automated systems have streamlined many aspects of finishing, masking remains a labor-intensive process.

But does it have to be that way?

“The reality of masking is that done right, it can provide an incredible competitive advantage.”

Rather than buying a generic plug or cap and hoping that it fits the part – sometimes the equivalent of fitting a square peg into a round hole – finishers can take their part to a custom masking supplier and come away with a mask designed exclusively for that specific item.

CARC Coatings

Type I CARC coatings are two component waterborne polyurethane chemical agent resistant coatings (CARC) for military equipment. Meets the performance and composition of the MIL-DTL-64159 Type I specification.

Key Features:
Low odor
Reduces with water, means considerable cost savings in solvent
Smooth finish versus standard CARC

Type II CARC coatings are two component waterborne polyurethane chemical agent resistant coatings (CARC) for military equipment. Meets the performance and composition of the MIL-DTL-64159 Type II specification.

Silk Screening

Silk Printing

The silk screen process is one of the most versatile of printing methods. Silk screen printing can be used on fabric, metals, glass and, of course, paper and cardboard. Large commercial screen print operations now use automated equipment, but hobbyists, artists and small shops continue to do silk screening by hand.

The Process

The stencil is attached to the under side of the screen. The exact procedure depends on the type of stencil used. The material to be printed is placed on the table, and the screen is lowered over it. A generous quantity of ink is put at the top of the pattern, but outside the printing area. The squeegee pulls the ink across the pattern and forces it through the silk onto the material.

Most screen printing jobs require more than one color of ink. Each color must thoroughly dry before the next color can be applied. Large screen print operations have a different screen for each color. In a small shop, the same screen is cleaned of the stencil and ink and then reused for the next color.

Sand Blasting

As a cleaning method, it is often used for priming a surface for the application of paint or a sealant.

When painting, one doesn’t want to trap dust, dirt, or bubbles in a previous layer of paint, or other imperfections under the new layer.

By launching small bits of abrasive at the surface at a high speed, all imperfections are knocked loose and can then be easily washed off,

creating an incredibly smooth surface upon which to lay the new layer of paint.

Blasting Methods

Bead Blasting

Bead blasting is the process of removing surface deposits by applying fine glass beads at a high pressure without damaging the surface.

It is used to clean calcium deposits from pool tiles or any other surfaces, and removes embedded fungus and brightens grout color. This process is notably used as an efficiently popular way to clean tile surfaces in swimming pools. It is also used in autobody work to remove paint.

Micro-abrasive Blasting

Micro-abrasive blasting is dry abrasive blasting process that uses small nozzles (typically 0.25 mm to 1.5 mm diameter) to deliver a fine stream of abrasive accurately to either a small part (mm size) or a small area on a larger part. Generally the area to be blasted is from about 1 mm to only a few cm at most. Also known as pencil blasting, the fine jet of abrasive is accurate enough to write directly on glass and delicate enough to cut a pattern in an eggshell. The abrasive media particle sizes range from 10 micrometers up to about 150 micrometers. Higher pressures are often required. The abrasive media is generally not recycled, since the particles tend to shatter on impact or lose their sharp edges. The most common micro-abrasive blasting systems are commercial bench-mounted units consisting of a power supply and mixer, exhaust hood, nozzle and gas supply. The nozzle can be hand-held or fixture mounted for automatic operation. Either the nozzle or part can be moved in automatic operation.

Powder Coating

What is Powder Coating?

Powder coat is electrostatically applied and then cured at various high temperatures to form a more durable and stronger finish than conventional paint.

Powder Coating is a durable weather-resistant coating designed especially for the general metal market.

Key Features:

  • Excellent corrosion and humidity resistance.
  • Excellent color and gloss retention.
  • Very good chemical resistance.
  • Weather resistant, especially designed for metal products requiring exterior performance.
 

EMI Shielding

Medical

Protecting operating theaters to shield EMI from stray or superfluous signals entering from another environment. Providing EMI Shielding vital for human organ monitoring equipment and systems.

Aircraft

Protection against lightning strikes on composite parts. EMI shielding of computer and communication equipment.

Aerospace

Protection against solar flares and power surges. EMI shielding on all mass critical parts or equipment.

Telecommunications

Shielding for digital and cellular systems (towers, antennas, monitoring and measurement devices, hand-held communications devices from microwave/EMI).

Computer

Reduction or elimination of EMI affecting computer hardware, software, peripherals and either hard wired or WiFi communication between various equipment such as printers, TV or audio systems.

Industrial Spray Painting

Industrial Spray Painting

BK Industrial Finishing has used many different types if material such as Po-lane, Urethane Lacquer, Bake Enamel, Urethane’s, Poly Urethane, Latex, and Oil Based. We have been working over 10 years to promote and change over to water-based. A Non hazardous coating with most all of our customer are happy to follow suit. Even Military Coatings used are water-based whenever possible.
