M390 stainless steel locking chucks.



M390 stainless steel closing mandrels (high quality stainless steel) manufactured in numerical control obtaining a high external quality of the closing head and its profile, with very low roughness on the mandrel lip, vacuum chamber tempering for obtain a greater uniformity of surface hardness and thus respect the narrow distances of the lip of the closing head with the body to minimize lip breakage due to bindings in the closed containers, tempered to 56HRC and subsequently rectified the outer profile of the mandrel and the interior where the axis of the sealer adjusts the mandrel lip in numerical control with boron plate for a minimum roughness necessary to reduce varnish depositions in the profile of the double closure head, which worsens the quality of the interior double closing once occasionally processed thus oxidations inside the bottom cuvette or lid.

We have a three-dimensional machine to make exactly the same profile that you are using or can send the plans of your packaging supplier and we will do it exactly the same respecting the tolerances marked on the plane.

We manufacture all types of closing mandrels of any brand and model of sealant, always complying with the same quality requirements and without distinguishing the price, for us all independent chucks of the sealer model have the same price.
