Milling

 

The aluminum and stainless steel materials that are used to mill the HPP series, embody the qualities of high-tech reliability that have come over the years to be associated with products bearing the legend: “Made in Germany”. Over 30 individual work processes are required to allow the extraordinary geometric contours of the HPP series to take form. Thanks to a 3-dimensional milling procedure performed on a high-speed milling machine from a solid lock of material, every head produced by this state-of-the-art machine is identical. Both versions of the putter heads are so detailed in geometric form, that it takes the milling machine around 2 hours to complete the aluminum Putter head and around 4 hours to complete the stainless steel head before they enter the handcrafting stage.

 

Handcraft

 

After the milling process, each putter head is individually hand-polished by specially skilled craftsman down to the finest detail. The importance of this

step ensures a perfectly worked surface that enhances the protective layering procedure. This polishing alone can take up to 2 hours per putter head.

 

Putter Insert

 

The filling of the insert is a special high-tech plastic-metal alloy mixture which is carried out by expertly trained craftsman. The liquid mixture is carefully poured into the milled head of the putter and is then allowed a hardening time of 10 hours.

 

Precision Ground

 

Once the mixture has cured completely, it is then precision ground to within 0,003 of a millimeter of the required dimension (loft). The insert offers a hard durable sur-face, which becomes one with the putter head, yet resulting in a very soft feel at impact with outstanding feedback.

 

Protective finish

 

The anodized heads (HPP 325) are treated with a special coating of transparent varnish, designed to protect the undercoating of the color from scratching easily, making it more durable. The classic based satin finish (limited edition) is a result of a multicoated galvanic procedure developed especially for this line, ending in a final layer of platinum. Extreme measures are taken to protect these highly refined materials which embody the form of ideas translated to perfection.

 

Putter Assembly

 

The putter mounting process is as important to Kramski as the exhaustive process of designing and producing the putter head. Both processes have to compliment one another. Hosels attached to the putter heads are still used by Kramski, because it is the best way to ensure accuracy of the shaft positioning. All shafts are precisely mounted with the help of a device (engineered by Kramski) to ensure a proper positioning of angle resulting in perfect face balance. Once the shaft is attached, the Kramski grips are then flawlessly mounted. Ensuring that the grip is horizontally and vertically perfectly mounted in relation to the putter head geometry.
