Metal Stitching: Why we Use the Best Stitching Pins in Existence Today

The Castmaster stitching pins that we use for our metal stitching repairs are manufactured by Lock-N-Stitch in the United States. They feature the patented Spiralhook thread, which makes them the best choice to carry out very strong, permanent metal stitching repairs.

This animation shows the working principle of the Spiralhook thread and explains why, unlike other products, these stitching pins do not create a radial spreading force during tightening.

 

These stitching pins are available in various diameters and lengths and are suitable to repair cast iron, steel, aluminium and bronze parts that are from 4 to 200 mm (1/6 to 8 inches) thick.

QuantiServ at the Sea Asia 2017 Exhibition in Singapore

Sea Asia Exhibition 4Our participation at the recently held Sea Asia 2017 in Singapore was a big success. We displayed our metal stitching and in-situ machining solutions, as well as the refurbishment of four-stroke cylinder covers by furnace brazing, which we are particularly proud of. These solutions created quite a lot of customer interest and led to many interesting discussions.

Our next stop will be the Norshipping Exhibition in Oslo, 30 May – 02 June 2017, where we will be at booth D 05-34. Come and visit us there.

A ship’s crew received a new cylinder liner in a mid-eastern port. Unfortunately, while lifting it onto the vessel, a sling came lose and the liner crashed hard on to the deck. Luckily no one was injured, but it caused a piece of cast iron at the circumference to be chipped off, rendering the liner unusable.

Instead of scrapping the liner, the Superintendent contacted QuantiServ and sent us pictures. After we confirmed that we could salvage the liner, he shipped it to our workshop in the Netherlands.

There our skilled machinists milled off a section of the liner and confirmed that there were no further cracks in the material. They then produced on a CNC milling machine a new piece that perfectly resembled the size and shape of the missing material. This they locked in place with glue and screws, thus saving a liner that otherwise would had to be scrapped.
