Delivering Key Engineering and Technology
Tools for designers, built by a designer.
Kenatec is an initiative dedicated to building solutions for industry, serving independent professionals and small companies — toolmakers, machine shops, plastic injection molders and metal casting.
Here you'll find practical look-up and calculation tools for mold and product development, plus content that's useful to anyone who designs: 3D models, software, tables and documentation.

Library
Every tool shows the formula behind the number and lets the designer override the parameters. No black boxes.
- Mold base
Which mold base to use
Projected area, product height and cavity count — or the part's .stl / .step — and out comes the series, sub-series and stroke of the standard mold base, with mold height and clamping force.
Open → - Sealing
O-rings and glands
Tell it what you are sealing — shaft, bore, face — and get the recommended ring and a dimensioned gland: depth, width, squeeze, fill and surface finish.
Open → - Retention
DIN 471 and 472 retaining rings
Shaft and bore retaining rings, groove dimensions with h11/H11 tolerance, and a shear check on the groove shoulder.
Open → - Fastening
Hex socket screws
Cap, countersunk, set screws and shoulder screws: clearance hole, counterbore, length by each standard's convention, and tightening torque.
Open → - Mechanisms
Plate puller
Set the size and both strokes of a sequential-opening puller and download the assembly as STEP, generated right in your browser.
Open → - Springs
ISO 10243 die springs
Pick the spring from the catalogue, get the load at each position, and balance layouts by comparing them — with load centre and moment on the plate.
Open → - Materials
Material weight
Block, bar, plate, tube and ring in tool steel, aluminium, copper and plastics — with each material's density and its source.
Open → - Materials
Compare materials
Mold steels by hardness and heat treatment, galling risk of the core pin × ejector sleeve pair, and the clearance for thermal expansion.
Open → - Thermalin development
Mold cooling
Channel diameter and pitch, flow rate for turbulent regime (Reynolds), pressure drop and heat balance per cavity.
- Dimensionalin development
Shrinkage and dimensions
Shrinkage by material family, steel dimension from the part dimension, and the resulting tolerance.
- Processin development
Clamping force
Projected area, estimated cavity pressure and minimum machine tonnage, with a safety margin.
- Fillingin development
Runners and gates
Runner sizing, balancing, and gate type selection by wall thickness.
- Mechanismsin development
Ejection
Minimum draft angle by texture and depth, ejector pin count and diameter by area.
