AMTS10 Specific Design Requirements

AMTS 10.0    Specific Design Requirements/Responsibilities

 

 

 

10.1  The customer will determine and specify part shrinkage on the mold design. It is understood that the part may not shrink according to the material supplier's recommendation due to mold construction, mold design, and processing. However, it is the responsibility of the customer to specify the shrinkage and pay for the tooling adjustments to bring the part into compliance. It is the responsibility of the tooling builder to execute the build of the mold in compliance to the shrinkage specifications of the design that the customer has supplied.

 

 

 

 

10.2  When multi-cavity tooling is built, each cavity must have unique identification on the cavity surface so that is molded into the part. The appropriate customer engineer will specify the size, and location of the identification.

 

 

 

 

10.3  Some molds have slides, pins, blades, sleeves, or stripper rings placed in front of hydraulic mechanisms such as, but not limited to, side cores.  If the mold has these mechanisms that can inadvertently actuate the hydraulic mechanism and cause damage to other components. The mechanism will have some confirming safety mechanism (such as a limit switch) to assure no interference or damage can occur in normal operation. In the case the ejector plate cannot be used to open the mold due to pins contacting a moveable feature. A plaque must be prominently mounted on the mold, warning of the damage that will occur.

 

 

 

 

 

 

 

 

 

10.4  All die models are the responsibility of the customer as to their accuracy and precision. It is understood that computer simulations are not guarantees of plastic shrinkage, heat exchange, or prediction of molded-in stresses. It is the responsibility of the customer to pay for adjustments required by the part after the use of such aids. The tool builder and designer are only liable for the appropriate use of these tooling aids.

 

 

 

 

10.5  As stated in the tooling agreement, all changes are to be authorized by Argo Mold. The definition of authorized, is that there are a formal drawing change, a written and authorized approval for the change, a quotation by the tooling source, and an appropriate adjustment to the purchase order to cover the financial impact of the change (a signed and approved purchase order amendment). The design of the mold is to reflect the most current engineering level and the part number. When an engineering change is started, the mold design, and the mold, is to be modified as part of the cost of the change. After they have approved and documented the part engineering change, the customer and the tooling contractor must also approve the subsequent change to the mold design.

 

 

 

 

10.6  Unless otherwise specified, the cavity will be finished to the customer’s specifications.
