Recent years have seen wider application of laser transmission welding (LTW) as a means for joining plastic components. Advantages of LTW arise from it being a contact-free method for delivering precisely controlled energy to the weld interface. LTW involves a laser beam passing through a laser-transparent component and subsequently being absorbed by the laser-absorbent component near the weld interface. Heat generated at the interface melts a thin layer of plastic in both co...

Laser welding is quite well established technology to join plastics. There are several different techniques to join plastics that have been demonstrated recently in different cases. The currently used techniques are contour welding, quasi-simultaneous welding, simultaneous welding and mask welding. Each of these techniques has their pros and cons. The product designers push...

Laser technology development in the field of plastics processing is now rapidly expanding and opens up a wide range of applications in various industrial fields that could not have been conceived of only a few years ago (automotive, plastic objects, packaging, ?). Among these processes, through-tr...

Petri Rahja, Iprbox Oy; Espoo Finland
Presented at ICALEO 2005

As being one of the most innovative countries in the world, Finland is also producing many inventions on the laser industry arena. The small home economy does not provide good enough business landscape for Finnish laser technology companies to grow. Finding global partners to startup new business is hard. In Finland, many good inventions have been left undone because of lack of global partners and investors. The presentation will introduce model created by iprbox to overcome the current barrier.

Is your business in an Early Market, Emerging Market, Mature Market or Declining Market stage? Is your business focusing on the stage you are in or some other stage? What stage is the customer in compared to the average for the market? Selling to the stage the customer is in is key to success.

We all know of businessmen successful with one company who start a new company or a new initiative in their existing company and fall flat on their faces. They had assumed all businesses are alike and/or that the new business was in a market at the same stage as the p...

Presented at ICALEO 2005

Asia is becoming one of the most important regions in the world from the political, economic and scientific point of view. Germany believes that it is becoming increasingly necessary to cooperate with certain Asian countries especially for scientific and technological reasons. Above and beyond exchanges of scientists, it is increasingly being organized to cover projects with specific targets and to find solutions to important problems. Inte...

Presented at ICALEO 2005

Laser direct deposition is good at manufacturing specific metallic components like refractory metal component with complicated geometry, which is very difficult or impossible by conventional method.
The paper presents research on producing high melting point Molybdenum alloy component by laser deposition. The temperature in a laser deposition melt pool is usually less than the melting point of Mo, so the fed Mo powder will not melt but dissolve into ...

Laser consolidation (LC) is a novel manufacturing process that produces net-shape functional and metallurgically sound components by adding material based on a CAD model. Parts are built layer-by-layer using a laser beam to melt injected powder and re-solidifying it onto a substrate. As an alternative to conventional machining processes, the LC process builds complete net-shape functional parts or...
