Such interior protrusions as breaker bars, dimples or ribbed sides should be used as necessary. Tests comparing internal barrel rinsing with traditional two-tank counterflow rinsing showed that internal rinse barrels require 30 seconds more rinse time; however, water consumption was reduced 1,400 gpd. c. Screw dryers are long tubes with a helical strip of metal inside. e. The rotation of the barrel while in the plating tank is also very important. Among those used are ASTM, SAE, AMS as well as corporate military and federal specifications. in. Subscribe to our newsletter and learn something new every day. To obtain the specific parameters, New Brunswick Plating (NBP) started by examining its casting machine.

Therefore, barrel plating is ideal for the electroplating of parts in very large quantities where surface appearance, plating distribution, and material costs are not critical. Today, the barrels used in this process have been replaced by plastic or composite containers. Typically a speed of 3 to 6 RPM is considered adequate but faster speeds facilitate a more uniform deposit even though there may be some physical wear on the barrel itself. Barrel plating systems generally require a lower equipment investment than other plating systems, which can be passed on to the customer in the form of a reduced cost for plating services. f. The tumbling action is also responsible for the high degree of plating uniformity which can be achieved in the barrel. b. b. Parts need only to be free-flowing enough to enter the mouth of the barrel. The milling process at NBP initially impacted its waste treatment. c. Immerse barrel next into another hot cleaner tank which is electrified in the opposite fashion of the plating tank so as to "de-plate" the parts and remove soils and some light scales. Today the company is heavy into barrel plating, although at one time barrel plating was restricted to smaller lots and never the preferred choice for plating. Also, the data link has to meet a 0.0003-inch bore tolerance. The zinc plating is applied anywhere from .0002-.001 thick depending on customer requirements. In the 1960s, NBP had the largest hard chromium plating tanks on the East Coast, and the company was heavily into aerospace plating. The loose laminate is not visible on the raw part, but would manifest itself as a casting blister when the highly stressed intermetallic is formed between the zinc base and the copper plate. This tumbling helps the metal ions reach the entire surface of the metal, allowing them to spread out more evenly and provide a more thorough coating. For example, the company developed a barrel plating process on zinc die-cast for Bell Labs optical fiber data link. Tsai determined that the variability was partially caused by ball valves, which were used to control flow. We strongly recommend this method on high volumes of parts, as barrel plating can accomate many shapes, sizes and metals. Decorative purposes hence adding a dazzling fresh shine on furniture. h. Because of the large amounts of parts, and thus the large amounts of surface areas being plated at the same time, the tank must be large enough to accommodate a greater amount of the metal being plated. Other key benefits include: To save customers money and guarantee predictable results, Sharretts Plating Company designs and builds nearly all of its barrel plating equipment. The metal ions form a protective coating on the new object, giving it new or enhanced properties, such as water resistance or corrosion resistance. We offer our clients a superior product due to our attention to detail and commitment to quality, supported by the highest level of customer service. g. The maintenance of the barrels is greatly reduced by constructing them of chemically resistant materials such as polypropylene, poly-glass, stainless steel and Koroseal coatings. Amazon Doesn't Want You to Know About This Plugin. c. The quality of the finish can equal that of still or rack plating and is usually more economical. Barrel Zinc Plate clear, ROHS compliant, per ASTM B633 The trial plating run also determined the amount of copper required to seal microscopic pores on the casting. For this reason, as well as economics. Barrel Zinc Plate black, non-ROHS compliant, per ASTM B633 Barrel plating is an inexpensive way to apply plating to small parts, usually to fasteners, screw machine pieces, stampings, springs and wire forms. e.

Horizontal barrels are the most frequently used, largely because they are capable of handling larger volumes and greater varieties of workloads. The original name New Brunswick Nickel and Chromium Plating Works was changed to the current name in the 1960s. d. Parts must be able to tumble freely to insure a good plating distribution. The company is dedicated to working with customers to specifically define and develop the best finish for a particular part. line with oversized tanks to accommodate large and heavy parts. This method might be used for large parts which could become tangled to assure they all are making electrical contact. Customers needing barrel plating services where plating specifications are complex and the finished product must meet very stringent testing guidelines and industry standards for industrial metal plating. When heavy machine manufacturing moved offshore, the companys hard chromium plating jobs dwindled. Some barrels have small metal buttons strung along their inside surface which are connected through a cable to an external power supply.

The holes must be properly sized so that parts do not fall through while being large enough for solution to easily drain to minimize wasted chemicals. For this reason platers keep a variety of hole sizes available along with a variety of barrel sizes.These sizes can include barrels with diameters of an inch up to monsters 24 inches wide by 60 inches long. Today, companies such as New Brunswick Plating, New Brunswick, New Jersey, develop better plating processes designed to accommodate the specific needs of its customers.

Large, rapid volume production in comparison to rack plating as a result is faster for production. Barrel Zinc Plate yellow, non-ROHS compliant, per ASTM B633 During post-Civil War era, thiscoated equipment made from wooden barrels or kegs therefore more availability and lower costs. Place loaded barrel into hot alkaline cleaner tank and rotate 3-5 minutes to remove oils and grease, then rinse in fresh water. As a result, we can service small prototype volumes with plating barrels the size of a fist to the largest of production jobs with barrel more than four feet long. Rapid advances were made in the field of barrel plating after WW II with the invention of chemically resistant plastic materials for equipment manufacture. It can also be used to alter the appearance or texture of some metals, particularly for jewelry and finished objects. As a very general rule of thumb, if a part can fit into the barrel, it is likely capable of being barrel plated. b. 2.

The four most important requirements are : Engineering applications, such as building up the thickness of metal to change the physical size of a part or to provide a good surface for some other treatment such as painting or screening.

f. Having plated the part you may now apply any number of post treatments including but not limited to: oils, waxes, sealants,chromates or other metals such as brass and chrome. Barrel plating generates 75% of New Brunswick Platings sales. This includes things like bolts, screws, and other types of fasteners. 3. In order to choose between them, we have take into account the size, shape and quantity of parts that are required for a project: Barrel plating is suited for quickly producing a high volume of parts to any size and shape specification, as compared to rack plating that favors more complicated, time consuming shaped parts. Normally, incoming zinc die-cast parts go through a 0.0003 inch chemical milling process, with dimensional loss being made up by an additional copper plate thickness. They enter the barrel through a hole machined out of each end of the barrel and are then connected to the rectifier which will supply the D.C. current to power the chemical process. Irregularly shaped objects also achieve better results with other forms of electroplating. c. Baking tests, notch tests, and ductility tests are also used to determine part utility. e. The exterior is shaped like a hexagon to provide a pumping action so plating solution can be replenished as the barrel rotates. New Brunswick Plating, Inc. began in 1932 by Martin and Harry Sica. Less labor is required compared to the rack plating process. The chemical milling process was developed by Bob Sica, then a plating chemist at NBP and now its CEO, and Allan Cook, a Bell Labs engineer who coordinated the die-cast changes necessary around the plating sequence. This is usually a coated cable with a large metal ball crimped onto the end which terminates inside the barrel and simply rides on top of the parts as they tumble in the cylinder. The entire plating process takes place inside of the barrel or vessel therefore only one person is needed per barrel. The number of holes should not exceed 30% of the surface area of the barrel or the structure of the cylinder may become too weak. The cascading motion produces a more uniformed metal finish in conclusion, the object has an even finish. The primary function of barrel plating is to provide an economical means to electroplate manufactured parts that also meets the customers specific finishing requirements. An overview of precious metal electroplating processes. Electrical contact was made to an outside D.C. power source to provide the energy for the plating process to take place. The research determined that the flows on different barrel plating lines varied and flows varied according to the time of day. Portable and miniature horizontal barrels are also available. Copper plating, nickel plating, electroless nickel phosphorous, palladium plating, palladium-nickel, silver plating, tin, tin-lead, tin-zinc, zinc electroplating, zinc-nickel, soft and cobalt hardened gold comprise the SPC plating array. It was about this time that barrel plating began, with platers using wooden barrels to finish parts. a. Plating standards for barrel finishing are in most cases identical to those used in rack and still plating. Two common types of plating barrels are horizontal and oblique. g. Unload parts into a drying unit and dry completely at no greater than 120 degrees F. a.

d. Centrifugal dryers spin the parts in baskets at speeds of up to 600 RPM while allowing hot air to be drawn through the load. Water use decreased by 5,000 gpd, saving more than $4,000 in sewer and water costs. As the parts move they make and break electrical contact creating what is called a bi-polar effect whose net benefit is the evening out of the high and low areas which could pose enormous problems if the same parts were to be racked and finished. c. In order to allow the plating solution to enter and exit the barrel without loss of the parts to be plated, holes are drilled along each side of the barrel and the removable panel called the door. Growth of Metal Plating : Future Predictions. Box, 157 3315 Connelly Rd. What are the Different Types of Chrome Plating Equipment?

This limit was established after tests showed that additional milling would expose minute internal air pockets in the casting.

or less can be routinely barrel plated. a. Barrel Zinc Plate yellow, ROHS compliant, per ASTM B633 Salt spray testing is widely used as a measure of a finishes fitness for use in the end product. Another method is to place large discs on each of the two sides of the barrel to assist in the plating of long thin parts which might damage internal protrusions. Chemical milling is an important step in the barrel plating process at NBP, because removing 0.0003 inch of material not only removes zinc oxide and carbonate on the surface of the parts, but also removes any minor base laminate surface that would produce a casting blister and minor flash. Proper and on-going training is extremely important to successfully barrel plating any part. The vessel is dipped in a number of different chemical tanks during the plating process. f. Barrel sizes and hole perforations should be chosen with care depending on the size of the parts to be plated. Rack wire electroplating offers a more complete method of plating for these types of objects.

Rotate barrel in acid dip which can contain such chemicals as hydrochloric, sulfuric, nitric acid, or dry acid salts. Every die-cast part undergoes a chemical milling sequence, with a removal limit of 0.00125 inch. a. In combination with higher levels of efficiency, there several other advantages to using the barrel plating method: 1. Electrical contact is made through the use of danglers/center bars that are located inside the barrel. d. There are numerous quality systems which the customer may require the barrel plater to employ such as the ISO 9000 standard which is one of the more recent attempts to help barrel platers achieve the highest level of customer satisfaction possible. Once the plating process is completed inside the barrel the parts are then removed to be dried externally. The end of the Civil War saw the need for increased production capabilities in the field of metal finishing. After plating a chromate film is applied to enhance corrosion resistance and give the parts cosmetic finish. NBP had the contract to gold plate retrorockets on the Surveyor Space Craft and satellite work from RCA Astro. Emigsville, PA 17318. Records should be kept regarding all of the important parameters involved in each step along the plating cycle. 1. The companys greatest strength is its adaptability to change. The benefit in barrel plating is the low cost to process, so long as the product is clean and ready to plate. Barrel plating is one of the most common types of electroplating processes. Rinse as before. The purpose of these chemicals is to remove any rust,activate the surface of the metal and neutralize any residual alkalinity left on the parts from the cleaner tanks.

Of the 75%, zinc die-cast-based material accounts for 65%, with the remainder being steel and copper-based alloys. b. This dedication pays off for its other clients as well, who benefit from the new plating process developments and improved processing methods. Both Barrel plating and Rack Plating have their own sets of advantages in the plating process. Like other electroplating processes, barrel plating helps to increase corrosion resistance or add strength to many types of objects. P.O. Barrel platingis versatile: plating several objects at the same time is highly achievable. Today, equipment is made of non-conductive and chemically inert materials. 6.

These should include things such as part description, load size, voltage, time, thickness readings, chemical additions and also any problems which may have taken place during the cycle. In the early 1930s the company gained expertise in the hard chromium plating process which was new to the industry.

Barrel platingis a cost-effective solution that allows for mass finishing of fasteners, small machined parts and small stampings. Call today to see how we can solve your finishing challenges. In the late 1800s, just after the Civil War, there was an increased need for finishing, particularly large lots of smaller parts. c. The surface area of the plated parts should generally be about 25 sq. These materials prevented not only deterioration of the barrels but minimized the solution absorption which used to occur in the older style wooden cylinders. This made it too expensive to use on all castings; however, a method was developed to treat the milling solution off line. This enabled the company to increase its customer base, which, in turn, increased its water use and subsequent wastewater discharge. Rinse thoroughly. 1010 Jersey AvenueNew Brunswick, NJ 08901(732) 545-6522www.nbplating.com. MnTap has a variety of technical assistance services to help Minnesota businesses. This method is well suited to manufacturers who produce large parts on a consistent basis because it has been found that the abrasion of smaller dry parts on each other is detrimental to the final finished product. One example is using zinc to coat steel, resulting in galvanized steel, which offers a much higher level of moisture resistance than uncoated steel. 7. Too small a barrel and the parts will not tumble properly. 125 cu. The barrel is usually vacuumed of surface water and placed inside a tank which blows hot air over its surface as it rotates very slowly. Items are placed in a slowly rotating barrel and immersed in theplating solution. It continues to develop new plating solutions and methods as well as innovative designs for lowering water consumption and decreasing costs related to waste use and waste generation. Agitation of the tanks solutions eliminate stratification and produces a homogeneous bath. Barrel Plating.Metal Finishing97.1 (1999): 346-67. Our Barrel Plating services help ensure that your finished part will meet your expectations and perform well when in use. 26 July 2015.
