What is 304 Stainless Steel?
304 stainless steel can hold the official title for the most popular grade overall and is certainly a hit with our customers. That’s thanks to its corrosion resistance and ability to handle high temperatures and corrosive chemicals. Whether it’s used in sheet form or molded into a fuel tank for a car, it’s a very versatile version […]
POM (Polyoxymethylene, Acetal) in CNC Machining
Polyoxymethylene (POM), also known as acetal, is valued for its high stiffness, low friction, and excellent dimensional stability. These traits make it a top choice for precision parts in industries like automotive, medical, and electronics. Whether it’s a gear or a valve, POM holds up under demanding conditions, maintaining its shape and function over time. […]
Nylon (Polyamide, PA) in CNC Machining
Nylon (Polyamide, PA) stands out for its high strength, flexibility, and impressive wear resistance. This makes it ideal for gears, bearings, and bushings, where reducing friction is key. Its ability to handle repeated stress and resist abrasion ensures long-lasting performance in mechanical parts. Nylon’s flexibility also means it can absorb shock, a valuable trait in […]
What is Laser Cutting?
Laser cutting allows cuts through a material with a concentrated laser beam that melts and separates a local part of it. In most cases, the process will be accompanied by a gas that blows the melted material out of the way, or the freshly cut material will be turned from a solid to a gas […]
Most Commonly Used Plastics in CNC Machining: ABS (Acrylonitrile Butadiene Styrene)
ABS (Acrylonitrile Butadiene Styrene) is a versatile plastic known for its strength and impact resistance. It’s tough enough to handle heavy use, yet easy to machine, making it a favorite for both prototypes and production parts. Found in everything from automotive components to electronic housings, ABS strikes a sweet spot between durability and affordability. That […]
Sand Casting vs. Die Casting?
Functionally, the differences between sand casting and die casting are extensive. Die casting uses steel cavities, while sand casting uses sand molds. Die-cast tools offer higher dimensional accuracy/repeatability than sand casts. They also have high durability, often allowing thousands of casts before reconditioning—whereas, sand casts are not reusable. Die-cast tools and equipment are very costly, […]
Why Plastics are Important in CNC Machining
Plastics are increasingly used in CNC plastic machining because they offer several advantages over metals. First, plastics are lightweight and more flexible, making them suitable for components that require movement or weight reduction. In high-volume production, plastics are far more cost-effective than metals due to lower material costs and shorter machining times. Additionally, plastics provide […]
Examples of Sand Casting Products
Examples of sand cast products abound in almost all market sectors, particularly in low-cost products and in heavy industries are listed below: Medium-speed marine diesel flywheels—can be several tons in weight. Through-hull nickel-aluminum bronze skin fittings in boat/ship hulls. Barbecue grills and burner components. ICE engine blocks. Vehicle brake discs. Door furniture. Decorative end pieces […]
The Factors Influencing the Cost of Investment Casting
The cost of investment casting is influenced by various factors. Material selection, complexity of design, size, and weight of the part all play significant roles. Production quantity affects economies of scale, impacting per-unit costs. Tight tolerances, high-quality standards, and specific surface finish requirements contribute to expenses. Upfront costs, including tooling, molds, and post-processing requirements, influence […]
Disadvantages of Sand Casting
There are various disadvantages and limitations to this casting method. These are: The surface finish cannot be particularly fine. Dimensional accuracy and repeatability can be variable. Contaminated sand waste represents a disposal issue. Patterns can degrade as production scales. Cooling rates are uncontrolled, so there is often variability in microstructure anisotropy. Complex sand cores for […]
