Polyethylene (PE) – a seemingly ordinary but ubiquitous plastic – has long been integrated into every aspect of our lives. From supermarket shopping bags to gas lines, from food packaging to artificial joints, it has become the world’s most widely used plastic material by virtue of its lightweight, strong, corrosion-resistant and low-cost advantages. By adjusting …
Polyethylene is, without a doubt, the workhorse of the plastics world. But not all PE is created equal—different grades boast vastly different properties, which in turn dictate their applications. Take Low-density Polyethylene (LDPE): its excellent flexibility, solid clarity, and ease of processing make it a go-to material for everything from packaging films and wire insulation …
In the 21st century era of industrial advancement, the size and quality of holes in components often determine the performance of the entire part. From bearing housings in automotive engines to hydraulic passages in aerospace systems, poorly machined holes can lead to misalignment, leakage, or premature failure. When drilling fails to meet precision requirements, and …
High-Density Polyethylene (HDPE) is one of the most widely used thermoplastic polymers in the world. HDPE belongs to the polyethylene family and is widely recognized for the strength, durability, and chemical resistance after processing. Engineers rely on HDPE for a wide range of applications including pipelines, chemical containers, packaging films, and CNC-machined parts. Its cost-effectiveness …
ABS (Acrylonitrile Butadiene Styrene) is a common thermoplastic engineering plastic in our daily life. With good mechanical strength, impact resistance and dimensional stability, ABS is widely used in the automotive, electrical and electronic, consumer goods and medical industries. When developing prototypes or mass production parts, engineers usually choose ABS as the preferred material for manufacturing, …
Teflon (Teflon) is the trade name of polytetrafluoroethylene (PTFE, Polytetrafluoroethylene). It is itself a fluoropolymer, with a very low coefficient of friction, well known for excellent chemical stability and resistance to high and low temperatures. PTFE performs very well in machining, assembly, and long-term service, and engineers often use it as the first choice for …
PEEK (Polyether Ether Ketone) is a high-performance engineering plastic that is often used as a substitute for metals in CNC machining. The strength of PEEK is comparable to aluminum alloys and some stainless steels, and its weight is half that of aluminum, which has important value in lightweight design. PEEK can maintain stable performance at …
1018 steel is one of the most common low-carbon steels used in CNC machining. It offers excellent machinability, stable cutting behavior, and low cost, making it ideal for shafts, pins, brackets, and general-purpose components. In the cold-drawn condition, 1018 typically has a tensile strength of ~440 MPa, yield strength ~370 MPa, and a machinability rating …
4140 steel is a chromium-molybdenum alloy steel widely used in automotive, aerospace, oil and gas, and heavy machinery. Its balance of tensile strength, toughness, and machinability makes it one of the most versatile engineering steels.
With proper heat treatment, 4140 provides reliable performance in demanding applications such as gears, shafts, and high-strength fasteners.
Aluminum, as a lightweight metal, is widely used thanks to its low density, corrosion resistance, and excellent thermal conductivity. In automotive lightweighting, aerospace, machinery manufacturing, and consumer products, cast aluminum and aluminum casting processes play a crucial role. From large engine housings to everyday furniture and cookware, cast aluminum parts have become an essential component …
