"To listen and take note of our clients needs and design specifications, generate ideas, solutions and execute them with a high level of detail and accuracy.
Since time is of the essence in today's manufacturing environment we strive to deliver on time every time."

ABOUT US

Based on the Gold Coast in Queensland, Australia, Austek Design was established in 2009 after working in the manufacturing industry for over two decades.

Having begun my career as an apprentice Tool & Die maker, I soon discovered I had a growing interest in the field of mechanical engineering design.

The natural progression from the drafting board was to use CAD as a design tool to produce designs that were accurate and time efficient.

The practical and theoretical knowledge gained from previous roles, gave me the confidence to provide design & drafting services based on sound principles and values.

Cutting Force
Blanking and piercing are similar sheet metal cutting operations that involve cutting the sheet metal along a closed outline or profile.
If the part that is cut out is the desired product, the operation is called blanking and the product is called a blank.
If the remaining stock is the desired part, then the operation is called piercing or punching. The scrap produced from piercing is called a slug.
Bend Length Calc

Bending is defined as the straining of the sheet metal around a straight edge.
Bend allowance:
This is the stretching length that occurs during bending. It must be accounted to determine the length of the blank.
Lb = ΣL+ΣBA
Lb is the length of the blank, L are the lengths of the straight parts of the blank, BA is the bend allowance.

Bending force

The maximum bending force is estimated as.
K x Lx UTS x T² ÷ D

K is the constant that depends on the bending process. K=1.33 for V-bending and K= 0.33 for edge bending.
L is the width of bending; UTS is the ultimate tensile strength of the material; T is the material thickness ; D or span is the die opening dimension as shown in the figure above.
