General:
1.1 Basic information:
1.1.1 Control of plastic mold building progress
The tool building progress has to be reported to Hesling BV every second week from the date of purchasing order. If there will be digital photographs needed, the supplier shall send them.
1.1.2 Packaging and transportation
The supplier will be responsible for effective and secure packaging of the tool suitable for transportation.
1.1.3 Product Responsibility
Supplier is responsible for delivery of plastic mold, which can meet under normal process conditions to the product specifications
Flow diagram:
1.2 Documents:
1.2.1 Drawings / CAD-files
The Supplier should execute all the drawings (files) necessary for the construction of the tool. Also hotrunner-, cooling-, hydraulic and/or gas assisted schematic plans are inclusive (A4- and DXF-format).
The CAD-files (2D and 3D) must be supplied on CD –ROM in native- and IGES-format, - eventual alternatives in agreed format.
1 copy (2D) in paper should also be supplied.
Moldflow report
This will be agreed between Supplier and Hesling BV.
1.2.3 Preliminary tool drawings
The preliminary tool drawing(s) should be assembly drawing(s) containing at least 2 plain views (injection side view + ejection side view) and 2 sections (longitudinal and transversal). The preliminary drawing(s) must show:
The functional design of the tool
The cooling system (incl. a separate clear cooling view)
The injection system
The tool dimensions
The lifting holes
Material/steel specifications
Hesling BV must sign the preliminary drawings for approval. This approval will be the start for planning of the manufacturing process and preparing / purchasing materials.
This should be executed within a max. 3 weeks time.
1.2.4 Final tool drawings
The final plastic mold drawing(s) should be assembly drawing(s) containing at least 2 plain views (injection side view + ejection side view) and 2 sections (longitudinal and transversal). The final drawing(s) must show:
The functional design of the tool
The cooling system (incl. a separate clear cooling view)
The injection system (+ detail section of gates)
The ejection system
Hydraulic systems
Gas assisted systems
Electrical system hot-runners and connections
The tool and main part dimensions
Lifting holes and security details
Materials and heat treatment according to tool standard/steel specifications
Purchased parts including technical specification
Progress Reports
Reference to paragraph 1.1.6 (in MS Project).
Trial Reports
It should contain process information, measurement reports and correction registration of product and tool.
Cooling Plan
The Cooling plan principle is shown in figure 1. The cooling plan must be delivered in a DXF-format (A4 drawing) 3 weeks before delivering of the tool.
Hot-runner Plan
The Hot-runner plan principle is shown in figure 2. The hot-runner plan must show the job number and whether or not the tips have been provided with torpedoes.
The Hot-runner-plan must be delivered in a DXF-format (A4 drawing) at FOT.
Make a clear hydraulic plan in case of use of valve pin hotrunner-system.
Tool base design
The tool shall be designed in a way that deflection does not cause flash.
Tool design for effective set up in machine and practical internal handling.
Tool design with correct closing on part surface for flash free detail.
Big tools must be made in tempered steel and the cavity placed directly in the tooling plates/blocks.
Reduce the contact area of the split line if it is too large in consultation with the project engineer.
The angles on cores/slides/blocks in the mould -steel to steel- contact should never to be smaller than 6.
If an angle smaller than 6 is unavoidable, then one side must be made of a brass alloy. Make this alloy in consultation with the project leader.
Insert parts (core/blocks etc.) on two side’s cone-shaped (ca. 5°), so that disassembling is easier.
Screw the spacer blocks between the back plate and the core plates to the core plate, so that these blocks will still be attached when the back plate is disassembled. This is for safety reasons.
For copper alloy use NSB4 (Zollern), AMPCO or Sankyo.
Preferred steel Suppliers:
Uddeholm
All steel should be delivered with a certificate from the Steel Supplier.
plastic mold Centering and plastic mold Clamping
Tool Centring
Cavity will be placed in the centre of the machine table. Both sides of the tool must be centered. The right construction of the centres-rings is shown in figure 19, page 26.
Tool Clamping
Tool clamping in the injection-moulding machine shall be done on the vertical sides of the tool if nothing else has been agreed upon. For further clamping specification, see Specific Technical Information and Machine-list. Special attention for tools eccentric placed on the machine (extra support blocks needed).
Hoisting holes and lifting bolts
The hoisting holes shall be at the top and bottom of the tool, seen when the tool is mounted in the machine. There must be hoisting holes in both tool halves, placed in the centre of gravity .
For bigger tools hoisting holes in all sides.
It must be possible to remove mould halves separately from the injection-molding machines. Therefore locate eyebolt holes in such a way that the separate mould-halves can be removed straight in line with gravity-point by a crane.
Tools heavier than 500 kg shall also have hoisting holes in the mounting plates.
Tool plates/parts heavier than 30 kg shall have hoisting holes.
Eyebolts shall be placed so they can freely be screwed and unscrewed even when the tool is clamped in the machine . All hoisting holes have to be dimensioned according to the tool/part weight .
Tool should always be placed save on the floor in the position when it comes off from the injection-moulding machine. Install standing-legs if necessary.
Hoisting blocks
The tool must be supplied with a hoisting block, which is placed on the top of the tool. In this hoisting block must be an eyebolt which is placed in line of the gravity point of the total tool. Hoisting blocks must be marked with the same Hesling BV mould code-number as the tool and painted red.
Isolating plates
The tool should be equipped with isolating plates on both sides. Dimensions: adapt plates minus T-mm.
Holes for centring-rings and assembling screws .
Lubrication and cavity protection
The tool (core / cavities) should be preserved with anticorrosion spray-wax agent (on silicone free base) specified for this purpose.
All ejector pins, leader pins and guide blocks should be lubricated with PTFE.
Coated tools for crystal clear products should be preserved with a coloured wax-type anticorrosion, silicone free agent.
Date stamp, recycling insert and Hesling inscription.
Use standard DME parts (see figure 6 and 7, page 12). Do not use diameters smaller than 8mm.
If needed, because of demand of customer, raster allowed.
Applicable material on material insert according Fig.7 or according specification Hesling Bv
Recycle logo placed around material insert. If this is unavoidable consult the project leader.
Painting
The tool should be painted.
Outside Tool: RAL 7016 gray high gloss.
Hoisting blocks: Red.
Tool marking
The tool should be marked:
Suppliers “plate” with details
Hesling BV “plate” with details (incl. mould-code number)
Eventual tool owners “plate” with details (to be decided by Hesling BV)
Plates should be placed in a good visible way on the top of the tool. plastic mold
