Type K3 / K3G

Base K3
Die sets with rear guide pins and top plate (P2) with profile.
The series K3 is manufactured with plates in SAE 1020 steel, pins and bushings in SAE 8620 steel, hardness between 58 – 62 HRC.
To further refine the construction of your tool, we also offer additional services such as: special Tooling, spare plates, wedges, lifting bracket, transport holes, among others.

More Information

General Information

Types of finishing

Type 3:Rough side with surface finish, thickness tolerance of ± 3 mm.
Type 4: Machined side with rectified surface finish, tolerance in thickness of ± 3 mm.
Type 7: Rough side with surface finish, thickness tolerance determined
Type 8: Machined side with surface finish rectified, thickness tolerance determined

* Tolerance of parallelism between the faces: ± 0.01 mm every 100 mm (up to 1200 mm) and ± 0.02 mm every 100 mm (above 1200 mm plates).
* Squareness between face and guide pins

Type

The die set type is determined according to the layout of the columns (Example: K3, K6, K8, K10 and K12).

Steel

The plates of the die sets are supplied in SAE 1020 steel or other types of steels by prior appointment

Assembly

There are two ways of assembly
Type 1: Without intermediate plate
Type 2: With intermediate plate

Tolerance class

The selection of tolerance between columns and bushing (Tolerance Class ) which is determined by the following way
CF.1 (small): Indicated for cutting tolerances less than 0.02 mm
CF.2 (medium): Indicated for cutting tolerances between 0.02 to 0,06mm
CF.3 (large)> Indicated for cutting tolerances between above 0,06mm

Tolerance for the drillings
Pins = T7
Bushings = H7

How to request using the suggestion of Polimold measures:

Example: To determine the Die set Code K3 with an useful area of 350x280 with P1 and P2 of 39 mm, Assembly of type 1, proceed as follows:

  • Locate the catalog the die set type to be used Ex: K3
  • Identify on Polibase table K3 the useful area: A2 = 350 e B2 = 280
  • Indicate the thickness of plates to be used: P1 = 3 (espessura 39 mm) e P2 = 3 (espessura 39 mm)
  • Choice the assembly type

Die set code: K3 3528 33 1
After you determine the Polibase, indicate the length of the Pin and bushing type being used.

Classification of thickness codes
Code
Thickness
1 24 mm
2 30 mm
3 39 mm
4 49 mm
5 55 mm
6 62 mm
7 75 mm
Choice the assembly:
Mounting 1: Polibase without intermediate plate
Mounting 2: Polibase with intermediate plate, additional plate provided always with thickness smaller a code below, in relation to greater plate on the die set.
NOTE: the intermediate plate mounting 2 will be provided with extra-small flange bushings. If the client does not specify another type.
