The Craftsmanship of FALTEC

Blow-Molding Technology

Blow-molding is used to form hollow objects through the use of air pressure, just like blowing up a balloon. The molten resin, before it enters the mold cavity, is called parison. Parison is a tube-like piece of plastic preform that is forced downward from the die head (die/core).

Die Slide Injection (DSI) Molding Technique

DSI molding is one of various injection molding techniques. It involves the realignment of the mold set and is useful for forming hollow, box-like shapes.

Gas Assisted Injection Molding (Gas Assist Injection)

The reinforcement ribs provided on the back of the molded part can easily cause sink marks on the decorative surface of the product. This type of injection molding ensures a clean finish--even to a decorative surface with ribs on the back--by providing a gas path (cavity).

Vacuum Vapor Deposition Technique

In the vacuum vapor deposition technique, metal is evaporated in a vacuum state and evaporated atomic particles are deposited on the preform (substrate). This makes it possible to give a bright finish even to the relatively soft surfaces of plastic products. FALTEC calls this technique “bright elastomeric finish surface treatment.”

Sputtering Technology

Sputtering technology makes high-energy particles collide with the surface of a cathode (negative electrode) placed in a vacuum, such surface being called a target (for example, a block of chromium metal), and deposits atomic particles ejected from the target surface onto the preform (substrate).

Roll Forming Technique

The roll forming technique is ideal for the high-volume production of window sashes, moldings and other long, narrow, constant-profile metal products that have the same cross sections no matter where they're cut.
Parts are formed by consecutive pairs (top and bottom) of forming rolls that resemble train wheels, and these forming rolls gradually shape the sheet metal.

Extrusion Technology

Extrusion technology is ideal for the high- and medium-volume production of long, narrow, constant-profile products that have the same cross sections wherever they're cut. This forming technology is used to apply plastic coatings to roll formed metal parts or to form plastic moldings. In addition to forming a fixed cross-sectional profile, we’ve developed a technology with which we can modify a part of that profile.
