...Unit 142: Plastic Processing Assignment 1: Moulding techniques used for the manufacture of plastic products P1 & P2 Plastic Dustbins The moulding technique used to make plastic dustbins is referred to as injection moulding. Injection moulding is the process where plastic is injected into a mould to form the final product. Both thermoplastics and thermosetting plastic can be used for the process of injection moulding. For this type of product HDPE is used, which is a thermoplastic. The material, usually in the form of pellets or granules, is dropped into the hopper. Heaters are found around the rotating screw; here the plastic is melted to a viscous state. Next, the plastic is injected into the mould and pressure build-up packs and holds the material in place.

...(i) Injection Molding Demonstration Battenfeld HM 40/130 is the machine used in the laboratory session to mold Polypropylene. Thermoplastic materials such as nylon, polystyrene, polythene and polypropylene can be used in a process called injection molding. How injection molding works? 1. The hopper is filled with granules of plastic powder. The hopper stores the material until it is needed. 2. The heater starts heating up the tube until it reaches a high temperature, then a screw thread starts turning. 3. The granules are pushed along the heater section by a motor, which pushes the granules along the heater section. The heater melts the granules until they reach the liquid state. This liquid is then forced under pressure into a mold where it cools down the liquid and solidifies it, which then turns into a shape. 4. The mold then opens and the ejector pins remove the molded part. In one molding cycle, the maximum amount of plastic injection mold that can be injected is called the “shot size”. For best quality, parts must use about 60% to 70% of a machines rated shot size. Larger shot sizes will not allow sufficient melt cushion for packing. Smaller shot sizes produce greater irregularities and loss of precision. The relatively high melting point of polypropylene allows continued use at 104°C. The resin begins to soften at about 121°C.

...1. Introduction Packaging has become an integral part of the processing, preservation, distribution, marketing, and even the cooking of foods. Food packaging materials include paper, cellulose products, cellophane, tinplate, aluminium, stainless steel, ceramics, glass, rubber, aluminium foil, plastics and laminates (Mercer, 1990). Since its introduction in the 1950’s, the use of plastic in the packaging industry has increased at a greater rate than any other packaging material due to their low cost and outstanding functional service properties (Hernandez and Giacin, 1998). Packaging materials provide protection for microbiological, chemical, and physical contamination (World Packaging Organisation, 2009). However, components of the packaging material must be safe to the product as well as to the consumers. Food may interact with the packaging materials and this may change the initial mechanical and barrier properties as well as the safety of the product (Sablani and Rahman, 2007). Three types of food packaging interaction are distinguished: (i) migration, (ii) permeation, (iii) and absorption. Migration is the transfer of chemical components from the packaging material to the contained food product (Paneva et al., 2005). The migration of potentially toxic substances from packaging material to foods is a major concern in the selection and use of materials for food packaging because of the possible effect upon human health. In addition, migration of other components...

...cycle repeats. Injection moulding is capable to repeatedly form identical discrete parts at a shorter turnaround time as compare to machining. Injection moulding not necessarily rely on one material, there’s variety of materials for example polymer and metals that can be used to produce parts. In this paper, the scope focuses plastic injection moulding by using polymer. Polymer [2] is adapted from Greek as ‘many part’, which describes molecule composed of many identical parts that synthesized together to from a large macromolecules. Generally plastic injection moulding uses thermoplastic and thermosetting polymers. The plastic parts that can be formed by injection moulding range from small electronic components such as lid of air-cavity package, to body panels of cars. Due to the capability of plastic injection moulding to generate big varieties of parts from as small as miligrams to kilograms, thus, a measure of size named shot size is selected which is determined by the weight of resin that can be injected per cycle. Shot size range between 20grams to 20kilograms. Figure 1: Injection moulding machine (Source: Modified from Wikipedia [1]) Basic plastic injection moulding...

...McGraw-Hill Companies srl 540 APPENDIX B Cases TREXEL We’ve never met a customer who wasn’t interested in our technology. —David Bernstein, CEO of Trexel David Bernstein hung up the phone with Alex d’Arbeloff, Trexel’s largest investor, and contemplated an upcoming Board of Directors meeting scheduled for June 25, 1998. The meeting was only 10 weeks away and Bernstein, Trexel’s president and chief executive officer, needed to present a coherent vision of the company’s new strategy. Bernstein believed that Trexel’s patented technology for manufacturing foamed plastics had the potential to revolutionize much of the worldwide plastics industry. His innovative process technology, known as MuCell, allowed the Woburn, Massachusetts company to produce foamed plastic utilizing 25% to 50% less material than traditional solid plastics without a significant decrease in the strength of the plastic. Bernstein believed the market for products produced via this technology could be in excess of 50 billion pounds of material per year representing potential worldwide annual revenues of over $100 billion. To date, Trexel had entered into numerous development partnerships with manufacturers, but no commercial products had made it to market. Bernstein was torn between his desire to pursue a variety of applications for the technology and the view of...

With the excessive use of plastics and increasing pressure being placed on capacities available for plastic waste disposal, the need for biodegradable plastics and biodegradation of plastic wastes has assumed increasing importance in the last few years. Awareness of the waste problem and its impact on the environment has awakened new interest in the area of degradable polymers. The interest in environmental issues is growing and there are increasing demands to develop material which do not burden the environment significantly. Biodegradation is necessary for water-soluble or water-immiscible polymers because they eventually enter streams which can neither be recycled nor incinerated. It is important to consider the microbial degradation of natural and synthetic polymers in order to understand what is necessary for biodegradation and the mechanisms involved. This...
