Different types of drawing lubricants are used depending on the depth of a particular draw.
Deep draw stamping lubricant.
Due to the quality of raw materials this product can handle a tremendous range of drawing and stamping applications.
The draw ratio must fall within acceptable limits to allow metal to flow.
Stainless steel deep drawing stamping lubricant.
The process is considered deep drawing when the depth of the drawn part exceeds its diameter.
Three types of drawing lubricants are used.
Deep drawing is a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch.
The draw ratio is among the most important elements to be considered when attempting to deep draw a round cup.
It is thus a shape transformation process with material retention.
When etna started operations in 1943 we began providing our drawing and stamping fluids and lubricants to produce shell cases for ammunition.
An array of applications including blanking piercing bending forming stamping and deep drawing.
Difficult chipless machining processes like drawing stamping finish blanking on iron and non iron materials as for plug and mandrel drawing stainless steel alloys.
The deep drawing test conducted at test speeds and with bhf comparable to those present in practical stamping is a reliable test for evaluating stamping lubricants.
Has over 70 years of experience developing formulating and manufacturing neat oil and water soluble oils for deep drawing and stamping operations.
However the sample dimensions must be selected such that the test can discriminate between different cof values provided by different lubricants.
Generally the effectiveness of a deep drawing lubricant depends on its ability to form an adsorbed film of sufficient strength and oiliness on the metal surface being drawn.
The draw ratio is the relationship between the size of the draw post and the size of the blank.
