• Laser Staking Securely Joins Plastic Parts for Printed-Circuit Boards
  in multipiece housings which may contain sensitive electronics such as sensors and lighting assemblies. Laser staking makes smaller bonds than laser plastic welding but uses the same underlying principle. Fingers, or stakes, in the injection-molded PCB housing align with holes in the PCB to stand above...
• Fiber Optics: Theory and Applications
  The science of fiber optics deals with the transmission. or guidance of light (rays or waveguide modes in the. optical region of the spectrum) along transparent fibers. of glass, plastic, or a similar medium. The phenomenon. responsible for the fiber or light-pipe performance is the. law of total...
• Glass Bubbles Reduce Weight of TPO Parts (.pdf)
  Resin compounder Noble Polymers of Grand Rapids, Michigan, a subsidiary of Cascade Engineering, has developed a low-density polyolefin resin formulation that reduces the weight of TPO plastic parts by up to twenty percent. This masterbatch bulk resin additive incorporates hollow glass bubbles from...
• Material Forming Processes
  Material Forming Processes. This text covers techniques such as injection molding, composites forming, die extrusion, hydro-forming, blowing, forging, machining and cutting, super plastic forming, as well as a number of other specific processes. Books24x7...
• Machine Shop Trade Secrets: A Guide to Manufacturing Machine Shop Practices
  Machine Shop Trade Secrets: A Guide to Manufacturing Machine Shop Practices. Written by an experienced machinist and plastic injection mold maker, this groundbreaking manual provides practical how-to information that can immediately be put to use to improve ones machining skills, craftsmanship...
• Plastics Consultancy Network - Mixing and compounding masterbatches
  A master batch is a product in which pigments and/or other additives are already optimally dispersed in a carrier material, that is compatible with the main plastic in which it will be let down and is supplied in either a granule or prill form. The carrier material generally used, is likely...
• Special Feature: Education/Training - Improve Work Performance with Continuous Training - 09/04
  offers special training involving an explanation of how plastic flows in an injection mold. If you challenge the reasoning behind this, perhaps the goal of cultivating a team environment will never be achieved. In this facility, there were mold builders and technicians who needed to work as a team...
• Fan Variants: What Type Of Drive, What Type Of Material? (.pdf)
  the specified values. In this way temperature dependent speed. profiles, externally set preset speeds and a variety of combinations of alarm and tacho functions can be. implemented. Plastic or metal. As well as the physical layout of the fan and the design of its drive, one very important...
• Hanil E-Hwa and 3M Team Up to Help Automotive OEMs (.pdf)
  OEMs. meet greenhouse gas reduction targets. Chal enged by a major automotive OEM customer to find innovative. ways to reduce parts weight without sacrificing mechanical or aesthetic. properties, a leading global supplier of interior plastic trim components. has achieved weight reductions of 5 ­ 13...
• A dry subject
  conditions. A key metric for plastic bearings called the PV factor characterizes a material's maximum wear rate and limiting temperature rise. PV (MN/m-sec) is simply the product of unit load, P (MN/m2) on the bearing projected area and surface velocity, V (m/sec). Moderate Temperatures, Light Loads...
