4.6 The Selection of the Injection Machine 4.6.1 Calculation of the Injection Volume Figure 4-8 shows the volume of plastic parts by Solidworks modeling. Figure 4-8 Volume of the Stress Cone Plastic parts volume: Vplastic = 4.198 × 10-5 m3 = 41.98 cm3 Plastic parts density: ρ = 1.2 g/cm3 Plastic parts quality: mplastic = ρVplastic = 1.2 × 41.98 = 50.376 g 4.6.2 Preliminary Estimation of the Gating System Although the gating system of condensate cannot determine the exact value prior…

While there are many types of plastics manufacturing systems [12], four of the most common are extrusion, injection molding, blow molding, and thermoforming. Together with roto- molding, these five plastics conversion processes accounted for sales in the United States of over 94 billion dollars in 2007 [13]; global sales of plastics products is several multi- ples higher [14]. 2.6 Method of Joining…

COSTS: Functional Elements: The baby stroller is mainly composed of three materials: Nylon (woven, as fabric) Plastic (injection molded, for plastic parts) Steel (tubing, for frame) Fasteners are included in the assembly of different components of the strollers. The stroller would have to be manufactured on an assembly line. The fabric weaving and seat making, the plastic molding and the frame can simultaneously be manufactured in their respective work areas. Following are the functional…

Life cycle inventory(LCI), Life cycle impact assessment and finally Interpretation. Goal and scope, is the start of an explicit statement and this will set up the scope of the product. Life cycle inventory is an analysis with the goal of listing the products to and from the nature. The outcome of this is typically a flow chart. Life cycle impact assessment, is pretty straight forward given the name. This is aimed to evaluating the potential environmental impact each step from the LCI flow chart.…

Christiansen’s Workshop. Ole Kirk Christiansen was a carpenter who started a toy business in 1932. They eventually found a new name for the company called Lego coming from the Danish word, leg godt meaning “play well.” In 1947, lego buys a Plastic Injection Molding Machine for making toys. In 1955, they made the first 28 lego Sets. They then modified the Lego Brick to have three holes on the bottom so that they will stick together longer. The Lego Company…

It requires three times the amount of water to produce a plastic bottle than to fill it, according to Hana Elisbury who wrote the article “10 Startling Facts About Bottled Water”. There are two ways to create plastic bottles; extrusion and injection. Billions of plastic bottles are used everyday, yet we rarely put much thought into how they are made. The process of making plastic bottles can be divided into three major steps. Assembling the material is the initial necessary step to creating…

Read-Write preference, I scored a 7. I was surprised by the results, as I have always considered myself as having a kinesthetic preference to learning. As a Section Leader in the injection molding plant, learning-by-doing was the best way to train employees. I was trained and have trained others, how to operate molding machines and how to measure and handle plastic parts using a more hands-on…
