What is electroplating?
Electroplating or electrodeposition is the process of coating the surface of an item by the action of an electric current. The coating that is deposited onto the material is usually metallic. Through electroplating, the metallic coating is applied to an object by putting a negative charge on the object and submerging it in a solution containing a salt of the metal to be deposited. The metallic ions in this salt carry a positive charge so they are naturally attracted to the object. This substance or coating follows the current and adheres to the negatively charged object.
How is electroplating achieved?
Electroplating is achieved through a method of dip-coating application in which paint solids are positively charged. The product is actually dipped into the coating mixture for one to two minutes and then rinsed. The electrochemical reactions that occur cause water-soluble resins to become insolubilized onto the object. The resin does require a subsequent cutting time.
How will electroplating save you money?
Electroplating is cost-effective because the unused paint can be recycled and used again on the next item. It is important to have a viable method for extracting the paint solids from the rinse water bath in order to reuse the paint. An effective electroplating system will have an effectual method for removing the paint solids from the water. The water from the rinse water bath can also be reused to save money in the process. This water can be used to rinse the parts after they have been coating.
Where is electroplating used?
Electroplating is used on a variety of products including automobiles, consumer electronics and construction materials.

Powder coating is an advanced way of spray-painting a very fine, dry plastic powder paint onto a metal surface that was first used in Australia in 1967. The powder used in powder coating is a plastic polymer, which comes in all imaginable shapes, colors, particle sizes and composition.
How does it work?
There are two techniques that can be used to apply the powder coating. The first technique involves electrostatically charged paint and a spray gun. As the powder paint cloud is released from the spray gun, it is charged with static electricity. The charge attracts the powder paint to the part that requires coating. Using the second method, the part is lowered into a fluidized bed of the powder, which may or may not be electrostatically charged. After using either method, the part is then placed in an oven, where it bakes at 400 degrees for 10 minutes. While in the oven, the powder paint melts and flows into a durable finish. Primers are not necessary and there are no unsightly runs or drips, as often results from the use of wet paint.
Prior to baking, powder coating is very forgiving of coating mistakes. Because it is powder, the paint can be blown with a low-pressure air nozzle, quickly and easily covering up the mistake. After the powder cures in the oven, it is almost impossible to remove. You can only correct mistakes by sand blasting or burning it off. Recoating over an existing finish is difficult but possible.
Why use powder coating?
- Powder coating produces a high specification coating, which is relatively hard and abrasion resistant.
- Powder coating is environmentally friendly because the over-spray is reused. Powder paint does not pollute the air because no solvents are used in the process.
- You can have virtually any color you want. If you have the budget and time to have the powder produced by a manufacturer, the choice of colors and finishes is almost endless.
- You can also select the thickness that is required for the individual part. Depending on the use or purpose of the item, you can determine if you are simply looking to protect it from rust or add resiliency and strength.
- Powders are simple to use and they do an excellent job of protecting your finished product for a long time.
- Powder coating will not peel, crack or chip like conventional paint, even under years of exposure to the elements. However, the coating should be washed every six months to ensure that durability, especially in industrial and marine environments.

Phosphating
We Offer the Following Phosphating Applications:
- Degreasing and Pickling
- Iron Phosphate
- Microcrystalline Phosphate
- Calcium Modified Zinc Phosphate
- Fine/Course Grained Phosphate
- Manganese Phosphating
Phosphating is an essential metal surface treatment process in which a layer of zinc, iron or manganese phosphate crystals are placed on the surface of the part to be painted. The phosphating layer increases corrosion resistance and improves paint adherence. The quality of the phosphating layer is essential for the final finishing of the metal product. All the processes prior to the application of the phosphating layer and the steel quality on the studied piece may have an effect on the result.
Generally, there are three types of phosphating:
- Iron phosphating is used to provide steel surfaces with good adhesion to paints.
- Zinc phosphating is used against corrosion and as a pre-treatment for steel and aluminum surfaces prior to painting or oiling for cold-flow pressing.
- Mangano-phosphating is used to impede the adhesive wear of mechanical parts of internal combustion engines or bearings.
The phosphating solution may be applied either by immersion or spray. Excess coating chemicals are removed in a water rinse. The main use of phosphating processes on aluminum is in situations where mixtures of metal, such as aluminum, iron, steel and zinc, are being processed together, for example in a car body assembly. Phosphate coatings on aluminum do not provide such good corrosion resistance as the chromate coatings, and in marine environments, an increased depth of pitting has been observed when phosphates are present.
The process forms a layer of insoluble phosphates on a metal surface using an agent containing phosphoric acid and/or phosphates. The pH value, rising on the surface, allows the formation and precipitation of the phosphates on it (and not in the bath).

Injection molding is a process that utilizes melted plastics injected into steel or aluminum molds, resulting in finished production parts. It is one of the most common methods of shaping plastic resins. Large machines called injection-molding machines accomplish injection molding. Approximately 40 percent of all plastics processed go through injection machines. The advantage of injection molding machines is that the molded parts can be produced economically in unlimited quantities with little or no finishing operations. It is useful when the parts are too complex or cost prohibitive to machine. With this process, many parts can be made at the same time, out of the same mold.
Since 1872 when the first injection-molding machine was used, the machinery has come a long way. The changing needs reflect the dynamic growth of the industry. Apart from its own normal growth, the molding machinery technology has been influenced by the advancement of other technologies such as hydraulics, computers and robotics. Injection-molding machines are consistent, accurate, energy-efficient and productive, ensuring customers get more product for their money.
There are six major steps in the injection molding process:
- Clamping (the clamping unit holds the mold under pressure during the injections and cooling).
- Injection (plastic material is loaded into a hopper on top of the injection unit, fed into the cylinder and heated).
- Dwelling (pressure is applied to make sure all of the mold cavities are filled).
- Cooling (the plastic is allowed to cool to form its solid form within the mold).
- Mold Opening (the two halves of the mold are separated, revealing the finished product).
- Ejection (the finished piece is ejected from the mold).

The forming process employs a series of stamping stations to perform simultaneous operations on sheet metal. The final work piece is developed as the strip of metal is processed through the stamping die. Many different processes are used to press or shape the metal into different shapes or forms for use in a variety of industries such as manufacturing cars to making children's toys.
How does metal stamping work?
During the operation, the upper die is attached to the ram and the lower die is affixed to the stationary bolster. The ram then moves vertically towards the bolster to form the piece of metal over the die. The metal is exposed to a series of die stations and each station changes the metal configuration left by the previous station. The metal work piece is created by the end of this series of stamping stages.
What materials can be used in metal stamping?
- Aluminum
- Copper
- Brass
- Titanium
- Cold-rolled steel
- Commercial steel
- Galvanized steel
- Cold-rolled draw steel

Rubber can be bonded to metal without a third bonding agent in order to isolate noise and vibration. Because of advanced technology, the process of bonding rubber to metal produces a high-quality product that is free from failure. Bonding rubber to metal requires precise heat control with temperatures ranging from 300 to 350 degrees F in order to bond properly.
How is metal bonded to rubber?
Induction heating is commonly used for bonding applications and has many advantages over other heating methods. Some of the benefits of using induction heating bonding rubber to metal include:
- Induction is reliable.
- The process takes a minimal amount of time.
- Induction is repeatable so the exact same product can be created over and over again.
- The process requires no contact between the machine operator and the object being bonded.
- Heating through induction provides energy-efficient heat.
The bonding process
The first step is cleaning the substrate or metal object. In order for the bonding process to work, the metal surface must be free of all traces of grease, oil or lubricant. The second step is applying the bonding agents, which begins with an application of a grey primer coat and a black topcoat. The rubber molding is then injected into the cavity.
What industries require bonding rubber to metal?
You may be surprised by the variety of businesses that use this technique in their products. Some of these industries include:
- Aerospace
- Agriculture
- Automotive
- Beverage
- Bowling
- Brewing

Tube Cutting
The objective of cutting tubing is to produce a square end that is free from burrs or rough edges.
How is it done?
Tubing may be cut using a standard tube cutter, a chipless cutter or a fine-toothed hacksaw. When using the standard tube cutter, the operator will place the tube in the cutter with the cutting wheel at the point where the cut is to be made. He or she will then apply light pressure on the tube by tightening the adjusting knob. Too much pressure applied to the cutting wheel at one time may deform the tubing or cause excessive burrs. The operator then rotates the cutter toward its open side, adjusting the tightening knob after each complete turn to maintain light pressure on the cutting wheel.
When you using the chipless cutter, an operator will take the following steps:
- Select the chipless cutter according to tubing size.
- Rotate the cutter head to accept the tubing in the cutting position. Check that the cutter ratchet is operating freely and that the cutter wheel is clear of the cutter head opening.
- Center the tubing on two rollers and the cutting blade.
- Use the hex key provided to turn in the drive screw until the cutter touches the tube.
How are lasers used?
Laser machines are relatively new in the fields of metal forming and fabricating. However, they are now used for cutoff, beveling and cutting slots, holes, notches, and other features of any conceivable size and shape in tube and pipe. They are most commonly used for cutting mild steel, the manufacturing industry's favored material.
Laser machines also are useful for cutting stainless steel, aluminum, and titanium.
Laser tube cutting machines for general fabrication work typically accept up to 20-foot lengths of tube and are equipped with load carriages that hold large quantities (up to 10,000 pounds) of tube. Many, if not all of these machines, can accept information in CAD format and use the information for nesting parts and developing cutting sequences and paths.
What you should look for in a tube cutting company
- Find a company who specializes in precision "cut-to-length" piece cutting of all types of ferrous and non-ferrous tubing and bar stock.
- Look for a reliable source that can save you time and money, optimizing your overall production piece cutting needs.
- Be sure the company you contract with ensures customers get the most reliable product. Every part should be 100 percent inspected at the machine, allowing for close tolerance requirements.
- Find a company who has state-of-the-art equipment to get your job done economically and efficiently every time. Their equipment should be equipped to perform complicated, multiple operations on one machine.

Mechanical tumble blasting
Mechanical tumble blasting is also a service we offer our clients because cleaning and pretreatment are essential when coating products. It is very important that every surface to be coated is clean because few coatings will adhere to dirty or oily substrates.
What is mechanical tumble blasting?
Mechanical tumble blasting with aluminum oxide or other abrasive particles is a common cleaning technique that ensures the even treatment of all parts. This method is often used for parts whose surface contaminants must be attacked physically to be removed such as rust, corrosion, scale and old coatings. Mechanical tumble blasting doesn't just clean a surface, it also roughens the surface and enhances mechanical adhesion by increasing the surface area to which the coating can cling. Mechanical tumble blasting can also be used to remove or blend surface irregularities, remove surface contamination or add a specific cosmetic finish.
How is blasting performed?
Mechanical tumble blasting is performed utilizing air-propelled media in specialized blasting cabinets. A variety of media can be used in this process including glass, steel, aluminum, sand, plastic, walnut shells and more. We use media in a variety of shapes and sizes as well as manual blasting cabinets and an automated tumble blasting system for the finishing of smaller parts.
