3.24 For molds built overseas and shipped to North America the Vendor is responsible to deliver
the mold cleaned up and ready for trial.
3.25 The Tooling source is to do a five piece CMM layout of parts from the 300 pc run. This
layout may need to be done in a free state if a fixture is not available.
3.26 It is the Tooling sources responsibility to produce a mold to these Standards. The mold
must produce a part that are dimensionally correct, flash free and meets the appearance
criteria of the OEM. These parts must be to the specified wall thickness, before and after
being textured.
3.27 It is the responsibility of the Tooling source to build a mold that will achieve a signed AAR
(Appearance approval Report) from the OEM or Tier One supplier to qualify a mold as
complete. It is the Tooling sources responsibility to make the necessary adjustments to
achieve a process that will produce a part capable of matching a gloss plaque and a signed
AAR.
3.28 It is the Tooling sources responsibility to manage the texturing source until a signed AAR
approval is achieved.
3.29 All molds must be certified to GD&T in car position with all check points agreed to by the
Minth Program Manager, Tooling Engineer and Minth prior to final design.
3.30 CMM certification of both Core and Cavity (steel checks) is required for all molds. Overall
length, width, attachment points and OEM significant characteristic points must be included
in layout. Layout and all schematics (water, electric, hydraulic) and final mold designs must
accompany mold for shipment.
3.31 Any preliminary tryouts by the tooling vendor for the establishment of wall thickness, shut-
offs, parting line match etc., shall not constitute fulfillment of the above tryout
MA-E-305 Revision 3 Page 16 1-JAN-2019
requirements. The cost of all additional tryouts to fulfill the above requirements will be the
financial responsibility of the tooling vendor.
3.32 If, after the mold is grained, it cannot meet the same requirements as outlined the tooling
vendor is responsible to correct the mold at his own expense and to incur all cost
associated in accomplishing the corrections
3.33 In the case of a two shot mold, the vendor is responsible for qualifying the substrate
through a dimensional layout of at least 15 parts prior to tuning it into the second shot
mold.
3.34 Warranty: The Tooling source is required to warrant the mold for the period of one year
and “mold life expectancy” of 1,000,000 cycles after the mold validation has been
completed at the Minth facility. This warranty includes any tier two suppliers that the vendor
may have used.
3.35 Therefore, the mold design, materials and components used in the construction of any
molds built for Minth are to ensure that the “mold life expectancy” of the mold can achieve
the 1,000,000 cycles.
3.36 The Minth designated mold shop is responsible to provide support in North America during
the one year period for any tier two suppliers.
3.37 The vendor is to supply a recommended maintenance manual and schedule for each mold
that outlines the preventative maintenance required.
