What is a plastic profile shape?

What is a plastic profile shape?

Custom plastic profile extrusion is the process of melting down plastic material and forcing it through a die in order to mold it into a desired shape and profile. The resulting product is then mechanically cut and finished to fit each specific order, with a wide variety of sizes, shapes, and colors available.

What are the types of plastic extrusion?

What are the Different Types of Plastic Extrusion?

  • Tubing Extrusion. This extrusion type is used for the extrusion of tubes and pipes.
  • Blow Film Extrusion. This type is used for the production of plastic films tubes through a continuous sheeting.
  • Sheet Film Extrusion.
  • Over Jacket Extrusion.

Can PVC be extruded?

One of the most commonly-utilized plastics, PVC is often extruded to form items that see common use across consumer, commercial, and industrial applications. PVC can be manufactured in one of two forms: rigid and flexible. Extrusion serves as an ideal means for creating PVC parts and products.

Why is PVC good for extrusion?

Rigid PVC extrusions have strong chemical resilience. This means rigid PVC tubing can be easily welded, glued and fused to itself – ideal for joints in pipes. Its resistance to corrosion makes extruded rigid PVC profiles, sections and trims suitable for outdoor environments.

What are extrusion profiles?

Profile Extrusion Process Profile extrusion is the process of making continuous shapes of plastic (not including sheet and film) by extrusion. Molten polymer is forced through a metal die cut into the linear shape of the desired finished article (channel, tube, etc.).

What are extruded profiles?

What is Profile Extrusion? Profile extrusion is extrusion of a shaped product that can be a variety of configurations but does not include sheet or film products. Profile extrusion can include solid forms as well as hollow forms.

Is plastic extrusion cheap?

Advantages of Plastic Extrusion Low Cost: Compared to other molding processes, plastic extrusion molding has a low cost and is more efficient. The extrusion molding process uses thermoplastics and they undergo repeatedly melting and hardening, this allows the waste to be reused rather than be discarded.

Which material is used in extrusion?

Hot extrusion

Material Temperature [°C (°F)]
Magnesium 350–450 (650–850)
Aluminium 350–500 (650–900)
Copper 600–1100 (1200–2000)
Steel 1200–1300 (2200–2400)

What are the types of PVC?

PVC pipes are generally categorised into four: PVC-U unplasticised PVC), C-PVC (chlorinated PVC), PVC-O (molecular oriented PVC) and modified PVC. Besides sharing many of the same properties, each type of PVC has its own advantages for different applications.

What is plasticized PVC?

Plasticized or Flexible PVC (Density: 1.1-1.35 g/cm3): Flexible PVC is formed by the addition of compatible plasticizers to PVC which lower the crystallinity. These plasticizers act like lubricants resulting in a much clearer and flexible plastic. This type of PVC is sometimes called as PVC-P.

What is the difference between rigid and flexible PVC?

The most notable difference is this: flexible PVC compounds have plasticiser added to them, while rigid ones have little to none. This plasticizer makes the PVC resin more flexible, which means it’s soft and supple in comparison. You’ll see these “rubbery” characteristics in the likes of garden hosepipes.

What is a hollow profile?

A HOLLOW profile is any extruded shape that contains a completely enclosed void anywhere in its cross-section. The void itself may have any sort of shape and the complete profile may include a variety of other forms.
