DME Item Number System

**MOLD BASES – “A” AND “B” SERIES**

The item numbers for Standard Mold Bases in the “A” and

“B” Series combine the NOMINAL Size (width and length),

the Series (A or B) and the thicknesses of the “A” (or

“A”-Clamping) and “B” Plates.

Since all the standard mold plate thicknesses are a

combination of a whole number and either

3

/

8

or

7

/

8

, the

designation 13 indicates 1 and

3

/

8

; 17 indicates 1 and

7

/

8

;

23 indicates 2 and

3

/

8

, etc.

**For Example:**

1016A-13-37 is the item number for a

9

7

/

8

× 16" “A” Series Mold Base with “A” plate 1

3

/

8

and

“B” plate 3

7

/

8

thick.

**MOLD BASES – “X” OR STRIPPER PLATE SERIES**

The item numbers for the Stripper Plate Series Mold Base

combine the NOMINAL Size (width and length), the letter

“X” for Stripper Plate, the numeral 5 or 6 (plate series) and

the “AX” plate thickness.

Since the “X” plate thickness is constant at

7

/

8

or 1

3

/

8

, and

the “BX” plate thickness is constant at 1

3

/

8

, 1

7

/

8

or 2

3

/

8

,

depending on the mold base nominal size and number

of plates in the assembly, these thicknesses are not

represented in the item number.

**For Example:**

1818X-5-13 is the item number for a

17

7

/

8

× 18", 5-plate “X” series Mold Base with a 1

3

/

8

thick

“AX” plate. (In this case, the “X” plate is 1

3

/

8

thick, and the

“BX” plate is 2

3

/

8

thick).

**“AX” AND “T” SERIES MOLD BASES**

The item numbers for the “AX” Series Mold Bases combine

the NOMINAL Size (width and length), the letters “AX” and

the thickness of the “A” and “B” plates. The “X-1” plate

thickness is specified when ordering and is omitted from

the item number.

**For Example:**

1212AX-13-37 is the item number for an

11

7

/

8

× 12" “AX” Series Mold Base with a 1

3

/

8

thick “A”

plate and 3

7

/

8

thick “B” plate. The “X-1” plate thickness

(e.g.

7

/

8

) is then specified when ordering.

The item number system employed by DME not only prevents the duplication of item numbers, but helps lessen the chances

of error in the writing and production of orders. This is accomplished by incorporating actual dimensional data into the item

numbers as indicated below.

The item numbers for the “T” Series Mold Bases combine

the NOMINAL Size (width and length), the letter “T” and the

thickness of the “X-2” and “B” plates.

Since the thickness of the “A”-Clamping plate is constant at

1

7

/

8

or 2

3

/

8

and the “X-1” plate thickness is constant at

7

/

8

or

1

3

/

8

, depending on the nominal size of the mold base, these

thicknesses are not represented in the item number.

**For Example:**

1012T-23-17 is the item number for a

9

7

/

8

× 11

7

/

8

“T” Series Mold Base with a 2

3

/

8

thick “X-2” plate

and 1

7

/

8

thick “B” plate. (In this case, the “A”-Clamping plate

is 1

7

/

8

thick and the “X-1” plate is

7

/

8

thick).

**CAVITY RETAINER SETS**

Since Cavity Retainer Sets are made up solely of an “A” and

“B” plate, the item numbers combine the NOMINAL Size, and

the “A” and “B” plate thicknesses. (The absence of the letter

“A”, “B”, “AX”, or “T” distinguish these numbers from the

item numbers of Standard Mold Bases).

**For Example:**

1215-33-47 is an 11

7

/

8

× 15" Cavity Retainer

Set with “A” plate 3

3

/

8

and “B” plate 4

7

/

8

thick.

**MOLD PLATES**

The same principle used for numbering Cavity Retainer Sets

is applied to Standard Mold Plates; however, only one plate

thickness is required. (Since the item numbers for retainer

sets will always indicate two separate plate thicknesses,

the distinction between these two items is easily identified).

**For Example:**

1318-47 is a 13

3

/

8

× 18" Mold Plate, 4

7

/

8

thick.

**NOTE:**

While an understanding of this item number system can be

very helpful in identifying and referring to the various standard

sizes, the DME catalog should be consulted when ordering

any standard item.
