GENERAL REQUIREMENTS:
1. Complete original tool drawings (hard copies) with the Methode Electronics format to be available with the moulds.
2. 3D CAD data of tool models in STEP format and 2D drawings in DXF format are to be available on a CD with the moulds. 
3. 3D mould assembly model to be available on a CD with the moulds and must conform with the mould supplied.
4. CAD data/drawings for EDM electrodes to be included on CD.
5. All requested CAD data is to be available also on our FTP site prior to delivery of mould.
6. 2D CAD data for the drawings to be on individual sheets. (Refer to Quality of CAD Data Guidelines).
7. Drawings to be in 1st angle projection.
8. All dimensions to be in mm.
9. Methode Parts List (BOM) format MB57 to be submitted with the CAD data in EXCEL format.
10. Any information/notes on the drawings to be available in English.
11. Drawings and 3D models of the tool layout should be submitted prior the design review meeting.
12. Design review should be documented and compiled on our standard format by supplier and approved by Methode Electronics together with the tool design layout for release prior to manufacture.
13. Design reviews should also include diagrams or sketches showing split lines, ejectors, injection point location, special areas/finishes, etc.
14. Critical dimensions that should be left with metal safe should be agreed during the design review. Fine tuning to be done in-house
15. Although Methode Electronics approves the tool design layout/design review, it is still the full responsibility of the supplier to resolve any issues or defects both on part and on tool until both are fully released.
16. Any plate having cooling channels to be manufactured out of corrosion resistant steel (1.2085 - Ramax S) regardless of previous instructions
17. Insulating plates to be on both halves.
18. Tool base to be standard from:
19. Clamping plates to be bigger than the tool base to clamp directly with cap head screws from the front of the machine platens - Refer to drg. no.
20. "Transport bar to be provided with an M12/ M16 or M20 hole for the eye bolt according to the weight of tool.
Tool serial no. to be engraved on hanging bar, whilst painted in colour according to our Colour Coding Diagram (Global number)."
21. Ejector plate to be guided with bushes and pins
22. All waterlines have to be connected with fixed or flexible tubes. Each mould half to have only one inlet and one outlet. Depending on mould size.
23. All parts subject to wear like inserts, cores must be designed as individual and replaceable single part in order to reduce maintenance cost to the lowest level.
24. Electrodes to be available with the moulds.
25. Mould release agent is not permitted.
26. Welding is not permitted.
27. Progress update to be supplied every fortnight starting from release of order (every 2 weeks) and every week for the last four weeks. Manufacturing process sheet to be used.
28. 3D CAD data in STEP format and 2D drawings in DXF format of the hot runner system are to be available together with the JOB No.
28. MEM Tool Tag which is supplied by Methode is to be affixed to the mould
29. Tag which is supplied by the hot runner manufacturer is to be affixed to the mould.
30. A wiring diagram for the hot runner system to be engraved on a separate template and affixed on the nozzle side facing the operator side and nozzle tips to be numbered accordingly.
31. Any discrepancies between the model and the associated drawing are to be discussed with the respective Methode Business Unit.
32. Moldflow analysis is mandatory and to be submitted together with the Design Review Meeting Minutes compiled on Methode standard format. So as the analysis to be conforming with Methode specifications as a minimum requirement it should consist of the following studies :  Fill Time / Pressure at V/P switchover / Temperature at Flow Front / Clamp Force : XY Plot / Volumetric Shrinkage / Air Traps / Sink Marks / Definition all effects . These together with an MFR file generated on same studies.   
33. No warpage and sink marks are allowed on the finished component particularly in areas of significant importance such as A surfaces and functional features. The subcontractor shall perform at his expense whatever type of research and verifications necessary to ascertain the part drg/design does not contribute to a tool design allowing for such conditions.           
34. Samples to be submitted according to contractual agreement.
35. All plates more than 15kg/ 33lbs should have threaded holes for handling.
36. Guide strips for sliding jaw tools should be located and grooves to be implemented for lubrication.
37. All cores and inserts have to be clearly marked.
38. A full measurement report with a marked up drawing to be carried out with first initial samples and whenever there is a dimensional change or correction on the tool, in the latter case this report is to be carried out only on the affected dimensions. For any case it is imperative that the same actual samples measured are to be properly labelled and clearly marked and sent to Methode accompanied with same Measurement Report  together with the usual requested 60 shots sample size.
39. Process setting chart MW169 should be filled accordingly and submitted with first initial samples, when conducting the OEE exercise and whenever there is a change in parameters. Refer to matrix for ideal parameters MW169.
40. Packing exercise should be conducted and information compiled in our MW169 Packing Graph Form in order to establish the holding pressures. This form to be submitted with the first initial samples and whenever there is a change in parameters.
41. Tool should be tried out for a minimum run of 8 hours unless instructed otherwise.  Information compiled in our MW69 Overall Equipment Effectiveness For Moulds. This exercise should be made when parts are dimensionally released.
GENERAL REQUIREMENTS cont:
42. Parts to be injected in a fully automated process and manual interventions by the operators are not allowed
43. A full shot sampled at start/stop and at one hour intervals should be checked visually and dimensionally. The CC dimensions generated from these measurements to be submitted in a report accompanied with the measured parts clearly identified for each hour.
44. A complete shot including runner to be available with every submission of parts.
45. Any interventions following the first off samples should be recorded on the attached electronic tool card under column titled Remarks. A copy should be sent whenever comments are added to the sheet.
46. This document is to be endorsed by supplier signature and returned to requisitioner before tool dispatch to assure that all the above mentioned  requirements were adhered and observed.
47. It is forbidden to use any type of  Friction Pullers for having pre movements of stripper plates etc. like for instance the HASCO Friction Pullers type  Z 172 . To use other alternatives like Round latches or other standard Latches etc.
48. All moulds are to be installed with a HASCO Cycle Counter type  - A 5730 / 47.5 x 38 x 24.5 (or similar) and to be fixed preferably on operator side.
REMARKS:
1. Important to take note of any comments listed in the remarks section in the part drawing.
2. It is important to note that Methode do not approve any serious alterations or retrofitting being done on the mould whilst being tested/ sampled
in order to accommodate a different type of 2K injection machine. The moulds needs to be designed without undergoing any serious conversion.
3. A separate Hydraulic system is available on the machine which can be used for ejection of parts if required.
4. Supplier to look into most feasible way so as to have the shortest runner as possible.
