CLASSIFICATION OF INJECTION MOLDS UP TO 400 TONS
.............................................................................................................................................................................................
The following contains a brief synopisis of the various mold
classifications and the detailed descriptions of each mold
class. Again, it is our recommendation that a MOLD DATA
SHEET (an example of which is in the back of this manual)
be included with each request for quotation.
CLASS 101 MOLD
*Cycles: One million
or moreDescription: Built
for extremely high production. This is the highest priced
mold and is made with only the highest quality materials.
CLASS 102 MOLD
*Cycles: Not exceeding
one million
Description: Medium
to high production mold, good for abrasive materials
and/or parts requiring close tolerances. This is a high
quality, fairly high priced mold.
CLASS 103 MOLD
*Cycles: Under 500,000
Description: Medium
production mold. This is a very popular mold for low
to medium production needs. Most common price range.
CLASS 104 MOLD
*Cycles: Under 100,000
Description: Low production
mold. Used only for limited production preferably with
non-abrasive materials. Low to moderate price range.
CLASS 105 MOLD
*Cycles: Not exceeding
500
Description: Prototype
only. This mold will be constructed in the least expensive
manner possible to produce a very limited quantity of
prototype parts.
CLASS I UNIT
INSERT**
*Cycles: Approximately
500,000
Description: Top quality
material for medium to high production requirements.
CLASS II UNIT
INSERT**
*Cycles: Under 100,000
Description: Similar
to class 104 Mold. Most commonly used insert. Low to
medium production.
CLASS III UNIT
INSERT**
*Cycles: Less than
500
Description: Similar
to Class 105 Mold. Least expensive insert for very limited
quanlities. Insert built with the least expensive materials.
**When buying inserts,
the customer pays only the insert. The unit mold base is
owned by the molder. Because of the large variation in
insert sizes, it should be kept in mind that it may be
impossible to have product produced by another vendor without
having to purchase a mold base.
(Important: refer
to the general specifications to complete the details
of this section, except for protype molds.)
