Polyethylene plastic comes in low-density and high-density forms. Low-density polyethylene (LDPE) was discovered in 1933 and is used for films, packaging, and laboratory equipment. High-density polyethylene (HDPE) was discovered in 1951 and is stronger than LDPE, used for larger items like pipes and automotive accessories. Both can be recycled but lose quality. Polyethylene plastic is […]
The plastic manufacturing process involves transforming crude oil and natural gas into polymer plastics, which are then molded into various shapes using injection, extrusion, blow, or rotational molding. Each process produces different types of plastic products. The plastic manufacturing process refers to the series of steps required to transform crude oil and natural gas into […]
Recycled plastic is now more expensive than new plastic due to the natural gas boom in the US, making petrochemicals cheaper to produce. This is problematic as packaging manufacturers are under pressure to reduce plastic waste. The world has produced 8.3 billion tons of plastic since the 1950s, but less than 10% has been recycled. […]
London Marathon organizers provided edible seaweed-based drink capsules to runners at Mile 23, reducing plastic bottle use by 2019%. The tasteless Ooho capsules can be eaten whole or bitten into for liquid release and decompose naturally in 4-6 weeks. When marathon runners reach Mile 23 of their grueling 26.2km race, they definitely need some water, […]
Plastic rivets are cheaper and effective fasteners, with different head types and colors available. They are usually installed by hand and need to fit snugly in the hole to hold properly. Plastic rivets are atypical for most manufacturing processes, but are important for cheaper riveting and can be very effective fasteners. The color of the […]
Choosing the right plastic adhesive depends on factors like strength, drying time, and the type of plastic. Adhesives made for specific plastics are available, and it’s important to consider bond strength, cure time, cost, and availability when making a decision. It’s helpful to consider factors like strength, drying time, and the type of materials you’re […]
Plastic gears are cheaper, quieter, and require less lubrication than steel gears. They are used in machines such as copiers and printers, and are ideal for lightweight machines and those operating in dirty environments. Plastic gears are also self-lubricating and easier to clean. A plastic gear is a gear that is manufactured from plastic. Plastic […]
ATV plastic refers to fairings attached to an ATV to improve aesthetics, aerodynamics, and protection. They can vary in size, shape, color, and design and may serve specific functions such as preventing mud and debris from hitting the rider. Aftermarket options allow for customization, but larger or intricately designed parts can be more expensive. Racing […]
Plastic business cards are durable and come in clear or solid varieties. Clear cards are basic but waterproof, while solid cards can be printed on both sides with high-resolution graphics. They are affordable and make a lasting impression. Plastic business cards are small cards made of durable plastic that contain a person’s name, job title, […]
Plastic tests determine the quality of plastic through strength, flexibility, durability, and temperature resistance. Different machines and techniques are used to test plastics for stress, impact, and light interference. Aging tests can also be performed to determine how well a sample will hold up over time and exposure to the elements. A plastic test is […]
Chroming plastics is possible through metallization or chemical plating, both requiring thorough preparation and electroplating with nickel and chromium. Metallization involves spraying a conductive layer of silver or aluminum paint, with silver being more expensive. Chrome-plated plastic offers advanced protection and is useful in industries such as automotive and toy manufacturing. Chroming plastics is a […]
Plastic pallets are becoming more common due to their advantages over wood, including lighter weight, environmental friendliness, and exemption from international shipping regulations. They are resistant to insects, bacteria, and water, and can be made from recycled materials. Traditionally made from wood or wood products, pallets are a versatile packaging material commonly used to transport […]
Plastic tweezers are non-conductive and non-corrosive tools used to pick up or remove small objects. They are popular in technical environments and scientific settings where metal tools aren’t safe. Plastic tweezers can also be applied to metal tweezers with plastic grips or tips. Plastic tweezers are simple tools made entirely or partially of plastic designed […]
To avoid discolored edges and improper cuts when laser cutting plastic for signs and awards, adjust the laser speed based on quality or quantity priorities. Different types of plastic react differently to laser cutting, and the table should be cleaned regularly and not reflect light. Engraving is common but requires proper alignment and mirroring for […]
Plastic injection molding involves heating and placing materials in a mold to create specific objects. The process was revolutionized by the screw injection machine in 1946, allowing for more precise control. Today, plastic is popular due to its flexibility, versatility, and low labor costs, but equipment maintenance can be expensive. When thermoplastic and thermosetting plastic […]
Plastic screws are lightweight, strong, and resistant to corrosion, making them ideal for use in consumer electronics and small appliances. They come in various materials and types, including pan head and hex head, and can generate significant clamping force when tightened. However, their strength is limited compared to steel, so they are not suitable for […]
A plastic chain conveyor is an industrial equipment that transports materials on a plastic belt or chain along a slotted track. It is versatile and can move in various directions. The plastic chain is powered by a motor and is suitable for light industrial and food processing environments. It has lower repair costs but can […]
The plastics industry produces lightweight, durable, and inexpensive products that can be molded into various shapes. It has existed since the 20th century, but humans have used natural polymers for centuries. Plastics are used in many everyday items, but their widespread use creates environmental concerns. The term plastic has become synonymous with man-made objects without […]
Plastic granulators break down plastic products for recycling. Plastic waste accounts for up to 40% of solid waste, and recycling is the only option to reduce landfill waste. Granulators turn plastic into flakes or granules, which can be sold to manufacturers. They consist of a motor, rotor, cutting blades, and a screen. Granulators can be […]
Plastic injection molds are metal shapes used to produce plastic items by injecting melted plastic into a precision-machined mold. Thermoplastics are commonly used and easily recyclable, while thermosetting plastics cannot be recycled. The screw-type method is now widely used for injection molding. Plastic injection molds are metal shapes created to produce a specific plastic item. […]
