Four Times a Custom Alloy Was the Right Choice

Posted by , on Oct, 2016

As a manufacturer, you sometimes need materials and products that are not easily available. If they happen to be metal, your purposes may require a unique alloy that must be custom-made. In this case, it is imperative that you trust a provider who creates custom alloys from top quality material. If you want your final product to be the high quality you need it to be, the materials used to compose any alloys should be totally pure, too. Here are four cases where a custom alloy may be the right choice. Medical Devices Because medical devices incorporate both biological and technological functions, their design must boast the utmost of precision. This is one of the reasons custom alloys have become a mainstay in the field. While other materials may be unable to produce the desired effect, one that is created for a specific purpose surely will. This is one of many places customized alloys are commonly used. Dental Implants Like alloys that are used in medical devices, custom alloys can be utilized in dental implants and restorations. They are particularly useful in casts and other parts of the manufacturing process that require a durable and resistant material. Creating a metal to suit this purpose is a great way to ensure your casts are reliable. The material is great for a range of other dental technology and product applications, too. Manufacturing There are a number of uses for custom alloys in the field of manufacturing. If you are looking for a specific part or a piece to perform a specific function, they are a great option. Customized alloys are useful, for example, by combining the qualities of one metal with those of another in order to produce a compound that meets your specifications. The possibilities are limitless in terms of the combinations and purposes that can be achieved with custom alloys. Be the first to like. Like...

The Advantages Of Rack Plating

Posted by , on Sep, 2016

While a lot of different metal finishing companies tend to favor barrel plating, there are many very good reasons to consider the alternative. Using a rack for the plating process provides several advantages, although it is certainly not the right process for everything that needs to be plated. The basic process of rack plating is more time and labor intensive than barrel plating, which means it is slightly more costly. However, with a well-organized and experienced metal finishing company this process is still efficient and it can be used to provide an extremely uniform finish to the tolerances required. The Process To complete the process, parts are placed on a specially designed rack. This rack is non-reactive and is used over and over again in the plating solution. Each component or piece is manually attached to the rack, which may also be called a plating jig. They may be hooked on attachments on the rack or individually fixed to the rack. This will depend on the shape and size of the component. Often this process is used for large parts or very irregularly shaped parts. The rack is then dipped into the bath for the time required. The parts are then removed from the rack, again by hand and further processed or packaged for shipping. Control of Part Movement One of the very big factors in using rack plating over barrel plating is the ability to carefully control any movement of the parts against each other. With barrel plating, the parts are simply placed in the barrels and then very slowly tumbled in the cage until they are plated to the desired finish. The problem with this method for very delicate parts, or for parts with multiple shapes and edges, is that the tumbling can cause damage. This can include areas that become bent or misshapen through the contact of the part with the parts and with the sides of the cage. Inspection An additional benefit to the rack plating process is the employee “hands-on” aspect of the processing. When placing the items on the rack or removing them after plating, any possible quality control issues will be noted. This is often not the case for parts that go through the barrel plating method. While plating metal components using the rack method is not the right process for all parts, it is important for specific types of parts. Always consider the risk to the parts of other plating methods before making a choice. Be the first to like. Like...

How Protecting Machinery Parts with Carbide Hardfacing Helps the Machinery Owners...

Posted by , on Sep, 2016

Heavy machinery and machines that encounter abrasive wear may need to be protected, and one way to do that is by using a hardfacing technique, also known as hard resurfacing. Hardfacing is a welding technique that entails adding filler metal material to surfaces of equipment. The filler material is added to the base material used to make the equipment. The procedure helps provide a fast yet efficient way of protecting compact equipment from wear, and for less money. Carbide is one of the products used to hard resurface a base material of equipment. Here are ways in which carbide hardfacing can help machinery owners: Improve Productivity When equipment such as bulldozers, grinding hammers, and trenchers have to be grounded because their parts are worn out, it means that a company may experience downtimes in its operations. The delays in working on projects can amount to reduced productivity. However, when the parts subjected to abrasion and wear such as bulldozer blades and trencher teeth are hardfaced, it gives them extra protection. This way, the machines can endure in their work ensuring that projects do not have to be delayed as other parts are sought. Reduce Costs of Operations If you have to replace bulldozer blades and other machinery parts that are subjected to wear, it becomes costly for your business. It can put a financial burden on your business if you will be replacing these parts every now and then. You can however, reduce the costs by ensuring that the parts vulnerable to wear are protected through a cost effective technique like hardfacing. Extend Life of Machinery Applying carbide hardfacing on machinery parts will provide a layer of protection meaning that the parts will not wear out fast. This way, the machinery and parts will operate for an extended time without needing repair or replacement. And, extending the life of machinery translates to lower operational costs. Investing in heavy machinery and other consumable components is something that requires a lot of money. Without protecting those equipment and machinery, it is likely to result in losses to the users. That is why the parts that are likely to wear out may need to have an extra layer of protection using the right material and technique such as carbide hardfacing. Be the first to like. Like...

Reasons To Choose A Certified Company For Metal Fabrication In San Jose...

Posted by , on Jul, 2016

Regardless of how small or how large a project or construction job may be, it is essential to always choose the best quality of fabricators and service providers. For commercial, residential or industrial projects in the San Jose and surrounding area, looking for an AISC certified fabricator is essential. There are several essential reasons to select an AISC certified company for all your metal fabrication needs. A quick review of the benefits will reinforce just how critical this decision will be for the job and the long-term ability to continue working with the fabricator for future projects. Rigorous Standards One of the unique aspects of certification is that it isn’t just something that is done once and then carries on with the company as long as they stay members of the AICS (American Institute of Steel Construction). Instead, this is an ongoing process. Every company that is AISC certified has to meet the standards on an annual basis. The standards for certification change over time to reflect current regulations, safety issues, training and quality requirements. By choosing a company with a current AISC certification, you are choosing a company that is committed to staying on top in the industry. Real Oversight To maintain this certification, the company must demonstrate they meet the standards as developed by the AISC. This includes attending trainings and using the latest in methods for both fabrication and installation. However, the company doesn’t just submit documents to prove this. There is actually an annual audit and a visit from the certification service to the company. This can happen at any time, ensuring the company is always using the most effective practices. Efficiency and Best Practices While it does take time, effort and money to be an AISC certified metal fabrication company, it also makes the entire company more efficient. By using the latest in technology and practices project waste can be reduced, new methods of fabrication implemented and a higher level of productivity can be implemented. There is often a difference in a quote between an AISC certified and a non-certified metal fabrication company in the San Jose area. While the certified company may have a slightly higher quote, they also have built-in advantages that the non-certified company cannot provide. This can lead to faster turnaround times, fewer budget overruns and a more efficient process for getting the quality fabricated parts you need for the job when you need them. Be the first to like.

Benefits Of Hiring Professional Roofers In Gig Harbor...

Posted by , on Jul, 2016

Most homeowners don’t realize it, but the roof on their home is a very important and complex structure. If a homeowner notices that there is a leak in the roof or any of the many telltale signs that their roof needs to be repaired, they have two options. They can watch videos online and make their roof repairs a DIY project, or they can hire Roofers in Gig Harbor. Of the two options, there are several reasons that they would better off hiring a professional. Knowledge and Experience It can be difficult to know the extent of the damage to a roof until the shingles have been removed, and the roof can be opened up. If the homeowner is attempting the roof repair on their own and the damage is extensive, they may not be able to handle the job. This is not the case with professional Roofers in Gig Harbor. A professional roofer has the knowledge and experience to handle a job of any size. Knowledge Working at Heights Repairing a roof can be a very dangerous job. Most roof repairs would take the homeowner up a story, often higher off the ground. When a homeowner is not experienced with roof repairs, they may focus less on their footing and more on the job at hand. It takes just one misstep for the homeowner to have a dangerous fall. A professional roofer has experience working at heights and the safety equipment to get the job done without any injuries. Saves Time Roof repairs can be very time-consuming. Most homeowners are so busy with their career, family, and friends that they don’t have much time for anything else. Because roof repairs are not one of the jobs that you can do a little bit at a time, it might be best for the homeowner to hire a professional roofer. Specialized Tools Most homeowners have a toolbox in their garage, shed, or basement, however, their toolboxes will typically consist of typical, everyday tools. To do a roofing job properly, specialized tools are needed. These tools can be purchased at a hardware store, but they can be expensive. When a homeowner hires a professional roofer to handle their repair, they can be sure that the roofer will have all of the tools necessary. When it comes to roof repairs, it is best to leave the job to the professionals. Be the first to like. Like...
