Cold forming is a cost-effective manufacturing process that uses punches and dies to manipulate metal at room temperature. It can produce a variety of products, including customized ones, and can work with different metals. Quality control measures are in place to ensure finished parts meet specifications. Custom products may be more expensive due to the […]
Cold rolling is a process used to change the thickness of metals or glass. Steel is fed through a series of rollers that press it into a pre-ordered gauge. Cold rolling complements hot rolling, refining the metal and improving the surface. The process strengthens the steel and eliminates cracks or variable patches. Steel companies use […]
Cold welding is a bonding process that uses pressure instead of heat to combine two metals, but not all metals are suitable. It is best for objects in space due to its limitations. Cold welding has been around for thousands of years and can be performed with less force or by raising the surface temperature. […]
Cold working is a metalworking technique that alters the structure of metal through mechanical stress, increasing strength and hardness while reducing ductility. It is cost-effective for high volume production but has a high initial capital cost and lower ductility. Cold rolling and cold forging are common methods used. Cold working is a type of metalworking […]
Cold forging involves shaping metal parts through compressive forces at or slightly above ambient temperature. It offers advantages over hot forging, including better surface finish, dimensional stability, and lower costs. Cold forming is suited to small to high volume parts and produces high-quality finishes with little post-treatment. Cold forging is a variation of the metal […]
A cold chisel is a tool for cutting unheated metal, usually made of hardened steel. It is less accurate than cutting machines but useful when they are unavailable. Different types of cold chisels exist, with the most common being the flat chisel, which can also be used for masonry work. They come in various sizes […]
A cold joint is a discontinuity between layers of concrete caused by curing before the rest is poured. It can cause visual defects, moisture infiltration, and compromised strength. Avoidance or mitigation is possible through waterproofing, surface preparation, rebar insertion, or strategic placement. A cold joint is an unwanted discontinuity between layers of concrete that occurs […]
To prevent the spread of cold sores caused by the herpes simplex virus, avoid skin-to-skin contact, practice good hygiene habits, and take medication. This includes not touching the blister, washing hands, and not sharing personal items. Children with cold sores should be kept out of school and toys should be sanitized. Medications can help reduce […]
Beijing historically heated apartments with coal-fired boilers, but is switching to natural gas. The central heating system is turned on from November 15 to March 15, with some exceptions. Residents pay around $500 USD for four months of heat. Newly built homes in the suburbs surrounding Beijing are heated by electricity, but historically coal-fired boilers […]
A cold air intake system draws cold air from outside the engine compartment, generating more power with minimal cost. Aftermarket systems use a free breathing air filter and a better location for the flow of cooler air. The factory offers a cold air intake kit for vehicle owners to improve performance. A cold air intake […]
Cold saws use circular blades to cut metal, keeping both the blade and metal cool. High-speed steel and tungsten carbide tipped blades are used for different thicknesses of metal. Water cooling systems are often used to further cool the blade and minimize dust and sparks. Cold saws are saws that use a circular saw blade […]
Cold rooms are refrigerated storage spaces used to keep items fresh for delivery or storage. They prevent spoilage and can be used in hospitals, warehouses, and other locations. Insulation is important to maintain a certain temperature and prevent energy waste. Refrigerated trucks are used for transport of perishable goods, flowers, meats, and human organs. Domestic […]
Cold finishing is a metalworking technique that involves changing the shape of metal without heat, resulting in a stronger finished product. This process can be used on various metals, including steel, and can be done by hand or with equipment that applies pressure. The end result is a smooth surface and components that resist wear, […]
Cold formed steel is made by rolling and stamping steel plates to the desired shape, making it lighter and more elastic than hot-formed steel. It is versatile and easy to deform, making it suitable for cars, transmission poles, and smaller buildings. Cold formed steel does not form with heat, like most other steels; instead, it […]
Cold sores are caused by the herpes simplex virus and are characterized by painful blisters on the lip. The virus is dormant when there are no symptoms, and it can be contracted through skin-to-skin contact. There are two species of herpes simplex virus, with HSV-1 being responsible for cold sores and HSV-2 being associated with […]
“Sore mouth” and “sore ulcer” are interchangeable terms for painful spots inside the mouth caused by irritation, stress, or medication. Cold sores, caused by a virus, are different and often occur outside the mouth. Chronic sores may indicate more serious health conditions. Prevention includes avoiding highly acidic foods and maintaining good dental hygiene. Treatment is […]
Cold metal cutting saws are lightweight, hand-held saws used to cut thin sheet steel without heating the blade or material. They preserve the sharpness of the blade and anti-corrosion coating on the cut edge. They are primarily used by sheet metal repairers for efficient cutting and trimming of thin sheet metal and corrugated iron often […]
A cold planer is heavy equipment used to rip materials such as roads and sidewalks. It has an adjustable head that can accurately cut to the desired depth. Large projects include a container to collect the material. It requires skill to operate and protective gear should be worn. A cold planer is heavy equipment that […]
Cold drawing is a metal forming process where metal is forced through dies to reduce its cross-sectional size, producing a consistent and defect-free product. There are three types of cold drawing: tube, bar, and wire drawing. The process improves yield and tensile strength, and is used in the production of various items such as electrical […]
Cold roofs prevent ice damming and structural damage caused by moisture seeping through the roof. Traditional cold roofs have a well-ventilated attic, while unventilated cold roofs use a breathable polypropylene membrane. Both reduce winter humidity and keep the building cool in warmer weather. With a cold roof, the roof temperature stays the same as the […]
