Our High Density Polyurethane Columns/Polyurethane column are purely decorative. High Density Polyurethane is an alternative to wood that will not rot, crack, or split. It is essentially a high density foam product with a density similar to white pine.
Architectural Polyurethane Columns remind us of the ancient world and if you want to add a hint of this to your project,our polyurethane columns(Decorative Columns, Porch Columns ,Architectural Columns,PU Fluted Columns, Ionic Order Columns,Classic Columns, Roman Columns) have designs with fluted or smooth,half and full Polyurethane columns with caps and bases to creat to suit your project.
Advantages of Polyurethane Columns:
1. PU (Polyurethane) material is Eco-friendly materials
2. Lasts longer than MDF or wood mouldings.
3. Designed for interior and exterior use.
4. Easy to install and will not crack, crumble, or warp.
5. Low cost: The surface painting is finished and installation time is very short, can be planned, sawed, nailed, and glued by yourself. 80% cost save than using wood and concrete.
6. Fire-proof: Reach the standard of no combustion.
7. Water-proof: No moisture absorbing, water permeation, and mildew arising.
8. Anti-erosion: Resist acid and alkali.
9. Light weight: good resiliene and tenacity, light and hard.
10. Styles and Colorful: Different Colors and Types are available.

In the polycrystalline diamond (PCD) tool series, progress is getting faster and faster. The first synthesis was in the 1950s, and PCD is now used worldwide and is seen as a powerful cost-saving tooling solution.
It is an unparalleled tool material for a range of non-ferrous workpiece materials such as aluminum alloys, plastics, reinforced plastics, ceramics, graphite and a wide range of other workpiece materials.
PCD tool characteristics
Diamond
Diamond is essentially a pure carbon. There are two known forms of carbon: graphite and diamond. In the graphite form, the carbon atoms are arranged in a hexagonal shape with a large atomic spacing in one plane, which makes the material very soft. However, in the case of diamond, carbon atoms are arranged in an equiaxed or cubic crystal structure. It is this unique arrangement of closely connected carbon atoms that makes diamond the hardest known material for humans. Its Knoop hardness, fracture toughness and thermal conductivity are shown in Figures 1, 2 and 3.
Preparation Process
PCD is obtained by artificial synthesis of a large number of randomly oriented diamond particles under extremely difficult conditions. It is prepared by sintering selected diamond particles at high pressures and temperatures. The sintering process is strictly controlled within the diamond stabilization zone, thus producing an extremely hard and wear resistant structure.
characteristic
Diamond in a polycrystalline form provides a powerful cutting tool that provides excellent hardness and resulting wear resistance combined with the excellent toughness of the polycrystalline structure.
In addition, diamond has the highest thermal conductivity of all tool materials, allowing heat to be quickly transferred from the cutting edge.
In addition to the high affinity of PCD and iron, PCD does not bond to the workpiece material, and under the correct cutting parameters, the built-up edge is minimized.
All Secomax PCD tools feature a mirror-finished rake face that provides the lowest coefficient of friction and a smooth cutting edge.

Aluminum alloy
Aluminum alloys have become an ideal material for the transportation industry to reduce weight. Although aluminum alloy production has greater initial demand for energy consumption, it has proven to be more beneficial in long-term operation, and these alloys will outperform other competing materials. Pure aluminum has low hardness and corrosion resistance. For example, the addition of alloying elements such as copper or magnesium will give the material a higher strength. There are many kinds of aluminum alloys on the market, the most famous ones are the 2000 and 6000 series used in the automotive and aerospace industries. There is a clear dividing line between forged and cast aluminum alloys, each with several different grades and a wide range of hardening properties.
For silicon alloys with low to medium silicon (Si) content, PCD provides the best wear resistance in milling applications and roughing, see Table 1.

To meet the challenges of today's world of environmental protection, the trend in automotive manufacturing is focused on reducing fuel consumption and reducing vehicle weight. These requirements are achieved by the development of new materials with higher mechanical properties. When the development of these materials achieves the desired goals, the downside is that these new materials are always stiffer and more resistant to processing.
