Different Methods Of Manufacture Of Metal Frames

Manufacturers have great differences in the way they make metal frames.There are 4 types of manufacturing used on inline skate frames,including folding,casting / moulding,exctrusion + CNC and CNC machining.

Some techniqes are cheap to do and also create bad products, like Foulding. And some technniques are harder to produce, but make great products, like CNC machining.

Folding

When one metal sheet is bent into a U shape and used as a frame, this is called folding. Making it affordable. Almost no material loss has occurred, yet it is not as severe.

A folded frame may be identified by the softened corners at the corner where the frame transitions from vertical to horizontal.

Moulding

When the exterior of the form is in the negative, like a coffin, molding occurs. The material is poured in, left to cool, and finally the finished product is produced. Cons: Moulded frames have a tendency to be fragile, making it easy for the thread to come out.

On the interior of the frame, look for markings that are typically 2 to 5 mm in diameter to identify a molded frame. The pusher pins used to extract the product from the mold left their imprints.A mold often contains several components. There may be two or even five components to it. Mold lines are clearly visible where these various components' edges meet.

Extrusion

Extrusion is carried out similarly to the making of pasta. Imagine heating up a large slab of metal to the point where it becomes malleable like clay. After that, this is forced out of a little hole.The form of the hole the metal bar is pushed out of may be used to determine the shape of the metal bar. The lengthy bar is then divided into parts the length of a frame, and the remaining material is removed using a CNC machine. Most frames on skates costing 200 euros or more are constructed in this way. The amount of material lost with this method is not significant.
If an extruded frame functions as a profile, you can identify it. As a result, when viewed from the front, a distinct, straight outline emerges.
Additionally, the tool that was used to CNC the rest of the shape's charming lines is visible.

CNC machining

Additionally, there is whole-computer machining. The material for this is cut from a single, solid block. You then take one large block and a large grinder and remove all the material. like how a statue of stone is carved. This costs a lot of money since it takes a long time and a lot of material, but it is also very, very sturdy.
The presence of several tool lines on a product identifies CNC machining. Although technology is capable of producing quite complex designs, the Wizard frames manufactured in this manner, for instance, have a fairly straightforward design. Pusher pins or mold lines cannot be found on a product that has been CNC-machined.

Manufacturing aggressive frames

On all surfaces, metal doesn't slide as smoothly and predictably as plastic. Because of this, all intimidating metal frames have the possibility of adding plastic add-ons. These might be plastic sliders or plastic H-blocks.
In this manner, you may benefit from both the metal frame's rigidity and the plastic's predictable grind.
