Rotational molding is a process used to create large, hollow plastic parts with uniform wall thickness. It is the only hollow parts process that can produce extremely large parts. The material is heated and rotated inside a mold to distribute it evenly. This allows for flexible designs by combining parts into one. Advantages include low-cost tooling, stress-free parts, and uniform thickness. However, cycles times are very long, ranging from 8-40 minutes. Also, only certain materials can be used and warping may occur without precise cooling. Competing processes like blow molding and injection molding have shorter cycles but cannot produce parts as large. Future developments include new materials, automation, and adding internal cooling.

The document discusses two tests used to measure the workability of concrete: the slump test and VEBE test. The slump test measures how much a sample of freshly mixed concrete sags or "slumps" due to gravity. The VEBE test also measures workability but uses vibration and timing to determine how long it takes for the sample to be remolded by the vibration. Both tests are affected by the amount of water in the concrete mix, with too much or too little water impacting the workability. The slump test is commonly used in the field while the VEBE test is better for dry mixes but less practical for field use.
CPP is a non-oriented plastic film that has better tear strength, impact resistance at low temperatures, and dimensional stability compared to other plastics like BOPP. It is produced through an extrusion process where plastic pellets are melted, filtered, layered and cast onto a chill roll to solidify. The film thickness is measured and controlled before the film undergoes surface treatment and winding onto rolls.
This document outlines a process for using plastic waste in road construction. Plastic films, foams, laminated plastics, and packing materials can be shredded and added to heated aggregates in a mixing chamber.

It then describes the main steps: plastic is fed into a hopper and pushed by a rotating screw through heating zones in a barrel before exiting through a die. Key components are identified as the screw, barrel, die and cooling unit. Extrusion is used mainly for thermoplastics to create continuous, low-cost products like pipes, films and plastic sheets.
Vacuum bag forming and pressure bag formingLahiru Dilshan
Vacuum bag forming and pressure bag forming are techniques used to consolidate composite materials. Vacuum bag forming uses vacuum pressure to pull resin-coated fibers into a mold cavity, while pressure bag forming uses both vacuum and positive air pressure to push the materials into the mold. These techniques are commonly used to produce parts for applications like medical devices, automotive, and recreation where higher fiber content and lower voids are needed compared to traditional layup methods. The processes involve laying up materials on a mold, sealing in a vacuum bag, and applying vacuum or pressure to consolidate the part before curing. They provide advantages like close tolerances and rapid prototyping for medium production quantities.
