The Realities of Modern Manufacturing

  • Globalization – Once underdeveloped countries (e.g., China, India, Mexico) are becoming major players in manufacturing
  • International outsourcing – Parts and products once made locally are now being made offshore (in China or India) or near-shore (in Eastern Europe)
  • Local outsourcing – Use of suppliers locally to provide parts and services

 

More Realities of Modern Manufacturing

  • Contract manufacturing – Companies that specialize in manufacturing entire products, not just parts, under contract to other companies
  • Trend toward the service sector
  • Quality expectations – Customers, both consumer and corporate, demand products of the highest quality
  • Need for operational efficiency – manufacturers must be efficient in in their operations to overcome the labor cost advantage of international competitors

Thermoforming - Vacuum Forming

berkaitan dg mata kuliah Proses Produksi with Dr.Eng.Ir. RUDI SUHRADI RACHMAT, M.Eng

Thermoforming describes the process of heating a thermoplastic sheet to its softening point, stretching it over or into a single-sided mold, and holding it in place while it cools and solidifies into the desired shape. The thermoplastic sheet is clamped into a holding device and heated by an oven using either convection or radiant heat until it is softened. The sheet is then held horizontally over a mold and pressed into or stretched over the mold using vacuum pressure, air pressure, or mechanical force. The softened sheet conforms to the shape of the mold and is held in place until it cools. The excess material is then trimmed away and the formed part is released. Excess material can be reground, mixed with unused plastic, and reformed into thermoplastic sheets.

Thermoforming is commonly used for food packaging, but has many applications from plastic toys to aircraft windscreens to cafeteria trays. Thin-gauge (less than 0.060 inches) sheets are mostly used for rigid or disposable packaging, while thick-gauge (greater than 0.120 inches) sheets are typically used for cosmetic permanent surfaces on automobiles, shower enclosures, and electronic equipment. A variety of thermoplastic materials can be used in this process, including the following:

Injection molding is the most commonly used manufacturing process for the fabrication of plastic parts. A wide variety of products are manufactured using injection molding, which vary greatly in their size, complexity, and application. The injection molding process requires the use of an injection molding machine, raw plastic material, and a mold. The plastic is melted in the injection molding machine and then injected into the mold, where it cools and solidifies into the final part. The steps in this process are described in greater detail in the next section. Lagi
