INTRODUCTION TO THE STANDARD BOOK FOR INJECTION MOULDS 1- The critical analysis will be performed by the supplier with suggestions from ARTEB engineering, but with total responsibility of the supplier based in the product drawing with RR (repeatibility and reprodutibility)
Obs.: ARTEB engineering can be asked to offer any kind of consulting during the mould construction (eg.: kind of steel, material input, extraction, etc.) however the supplier is responsible for the mould performance and process.
2- The supplier must include in the final project, the drawing of the hot chamber with its map respecting the pattern mentioned in the standard book which has been delivered with the pre project for quotation.
3- The mould only will be released for the 1st try out at ARTEB, after the visit of ARTEB engineering, which will verify: refrigeration test in process temperature; cavity finishing aspect (as product drawing); mould identification plate as ARTEB standard, plate with refrigeration map as ARTEB standard, plate with hot chamber map as ARTEB standard, connections of the refrigeration system as ARTEB standard, connections of the hydraulic male system as ARTEB standards, electrical installation (hot chamber, heating system by resistance, end of course micro) as ARTEB standard; tappings and micros fixation;
dimensions manifold or refrigeration couplings Staubli as ARTEB standards, mould fundamental dimensions as book, centering ring dimensions, as ARTEB standards, groove or fixation flap dimensions as ARTEB standards, type of coupling for extraction as ARTEB standards, kind of lubricant applied on the mobile areas (extraction, slides, male part of the moulds, etc) as ARTEB, type of protective anti-corrosion for the cavities as ARTEB standards, performance of the mechanical parts of the mould.
4- For each try out at Arteb, the supplier should send a tollmaker for following it besides making little adjustments when necessary.
5- The approval for the mould payment after 2.000 cycles, taking into consideration the rate of rejected parts after the process stabilization
Obs.: a- Such rate can vary from 1,5 to 2% (depending on the department) for the thermoplastics and 1,5% for the thermofix (BMC)
b- The injection of 2.000 cycles for approval will be counted only after the try out report by all the involved departments at Arteb (Tooling room, manufacturing, product engineering, process engineering and quality)
6- The mould guarantee (functional, material, cycling) will be of 500.000 cycles Obs.: The supplier should guarantee the cycling timing indicated in the project 7- The final approval will be made only in a lot produced at Arteb.
Obs. 1 – All the above mentioned information is valid for internal and external suppliers
Obs. 2 – The books will be subject to revisions (in the quotations and moulds projects it is very
important to verify if the revisions of the standard book cover are identical to the ones
in the book)
