 ALWA-MOULD D / ATLAS M 130

 Casting resin for different applications
 01. Fields of application
 Vacuum forming, soft, flexible and rigid polyurethane foam, holding fixtures, models for digitalizing and
 duplicating, prototype moulds for blow moulding and compression moulding, works of art, such as
 sculptures etc.
 Advantages:
 Can normally be demoulded within 45 minutes after post curing. Post cure unnecessary, very low linear
 shrinkage, excellent dimensional stability under heat, low coefficient or thermal expansion, true mass cast
 system.

 02. Description
 ALWA-MOULD D / ATLAS M 130 a two component resin systems based on methyl methacrylate, with
 fillers for the production of moulds. After addition of the hardener, the mixture sets quickly at room
 temperature. A self indicated exothermic cures the mould. Two formulations are developed to provide
 optimal performance for the desired application. Any thickness and volume from 1 kg – 2000 kg can be
 cast in one pour. Easily machine able, good heat conductivity when copper lines are cast in, tension free
 moulds, excellent reproduction of details and low viscosity for easy pouring.

 05. Patterns
 Patterns can be made of nearly any material (wood, plaster, leather, metal, plastics, casting resin and PU
 foam, except polystyrene or acrylics which require special precautions. Porous surfaces should be sealed
 with ALWA Acrylic sealer, I.-No. 9535 or a similar product and, if necessary, sanded and recoated. All
 materials must be dry. All patterns must be pre-treated with Surface tension remover, I.-No. 9500, which
 removes the surface tension and ensure a smooth coat of Release lacquer, I.-No. 9510 (applied with a
 brush or spray gun) after the surface tension remover has dried thoroughly. Defects in the moulds can be
 avoided by using materials with similar thermal conductivity for the pattern and the mould box. If necessary
 reinforcements (only perforated aluminium sheets 2 – 3 mm) can be casted in. Other materials are
 attached to the mould after it has cooled down. Take care with the different thermal expansion of the
 different materials used to mount the mould. Drill bigger holes for screws when other materials are
 connected to the casting.

 06. Heating and cooling of the moulds
 Copper tubes for cooling and heating can be casted in (distance from the surface 10 – 30 mm, copper
 tubes soft, I.-No. 9210 – 9212). Electric heating and cables can be casted in, if the surface temperature of
 the heating system is not higher than 130° C. When the mould is heated from the back the surface of the
 mould has to be plan.

 07. Calculation of the preparation quantity (standard formulation)
 a)      Calculate the volume in litre. We recommend adding 5 % more to cover losses and miscalculations.
 b)      Calculated volume x 1,7 weight kg/l = quantity of the preparation / kg
 c)      Preparation / kg = 40 % resin ALWA-MOULD D / ATLAS M 130, Comp. 1 + 2 and 60 %

 08. Processing
 The resins need to be shaken/mixed before use. Mix the filler homogenously into the resin. Leave the
 finished mixture for a period of approx 1 – 2 h for degassing. Very important!!! Mixture temperature 19 –
 21° C. At higher temperatures the mould gets shrinkage and a lower expansion. After this period,
 thoroughly mix the degassed mixture (approx 3 – 5 min), until the aluminium sediment is mixed in
 homogeneously. Then add the hardener. Do not mix in lumps of hardener. Do not stir in air. Large
 quantities can be mixed in two or more big buckets. Important! Mix in the hardener simultaneously. Mix
 after addition of hardener all mixtures among each other to achieve the same temperature and reaction of
 the mixture.




 When mixing equipment is used we recommend the use of our special mixers. After the hardener is mixed
 in properly and a degassing time of 3 min., the mixture must be casted within 10 – 12 min. To eliminate
 small air pockets at critical points on the pattern surface (narrow ribs, fine details, corner, edges) these
 areas should be brushed with the resin mixture before casting begins. Pour the resin mixture slowly into
 the deepest part of the pattern. Pour if possible only in one place (will remove any remaining air). When
 the pattern has been completely covered, the rest of the mixture can be poured in more quickly. The
 mixture starts to gel 18 minutes after addition of the hardener.
                                                                                     (to be continued on next page)

 ALWA-MOULD D / ATLAS M 130

 08. Processing
 Do not heat or cool the casting while curing. Reaction temperatures of approx 130° C can be reached.
 When the casting is cured (approx 50 minutes after addition of the hardener) spread aluminium powder on
 the back side of the mould (to avoid sticky back surfaces). Demould after the highest reaction temperature
 is reached. Clean tools and buckets with acetone before the resin cures.

 10. Curing and demoulding
                                                                  C        C),
 When the casting reaches its highest reaction temperature (125° - 130° the mould will expand in
 length and the mould box ends should be released to allow this expansion. If this is not possible,
 demoulding should take place in this moment and the mould should be placed immediately on a flat
 surface. Great care is required during this process since the mould is hot and distortion can easily occur.

 Lay the mould flat immediately and carefully clamp it down. Thin moulds should be poured, close or
 covered with thick plywood. Demoulding normally can take place after the mould has started to cool down.
 As long as the mould is still warm, it must remain on a level surface. Never place a warm mould directly
 onto a metal surface. When the mould cools down to room temperature the expanded length will return to
 its original shape. The self generated exothermic heat provides a complete cure so that no post cure is
 necessary.

 Note: The linear expansion is a one-time occurrence caused by the exothermic heat generated during the
 cure cycle. Since the resin mixture sets at room temperature, even sensitive patterns such as wax or clay
 can be accurately reproduced.

 11. General information
 Finishing mould
 A mould made from standard formulation can be drilled and tapped, but it is preferable to cast bolts into
 the tool. The highly filled formulation is hard to drill and tap and all bolts, etc. should be casted into the
 mould. Moulds can be easily machined by the normal methods. Due to the dust developed during this
 operation, a local exhaust should be provided.

                                                                                            (to be continued on next page)

 11. General information
 Temperature control of tools
 For the temperature control of moulds during production, copper tubes can be casted into the tool.
 Minimize the temperature difference between inlet and outlet since varying temperatures in the mould can
 have a negative effect the quality of the finished parts. Copper tubes should be casted in, at a distance of
 1 – 2 cm from the pattern surface and 3 – 4 cm distance from each other. In the case of larger tools, these
 copper tubes will improve thermal conductivity. If direct cooling is not possible, heat transfer can be
 improved by machining the reverse side of the mould and mounting it on a metal plate. An alternative
 method of heating moulds is to cast in electrical elements. For to drill vacuum holes use special drillers,
 I.-No. 9006 – 9015. For thin moulds use a closed mould box or cover the mould and clamp down after it
 sets. If Demoulded early, place it flat on a table immediately, cover and clamp down.

 Repair instruction
 Normal repairs can be made with repair filler, I.-No. 3050. The damaged area should be thoroughly
 cleaned and roughened before filling with patching compound.

 12. Safety measure for processing
 ALWA-MOULD D / ATLAS M 130 contain methyl methacrylate and styrene and are classified as a
 flammable liquid. During use, avoid sparks, fire or any source of ignition. Only air-driven mixers should be
 used. Smoking should not be permitted. Aluminium powder must be handled carefully to avoid formation of
 dust clouds. It should be kept away from water, heat, open flame and sparks. Smoking should not be
 permitted. Hardener powder is a high reactive material and any contamination must be avoided. Ensure
 good ventilation. Close all containers tightly after use. For further details, consult the respective material
 safety data sheets, as well as the “Recommendations for storage and handling of aluminium powders and
 paste” published by the aluminium association. Works areas should be clean and well ventilated. The use
 of gloves is recommended as resin should not get on the hands. If it does, use an industrial skin cleaner
 along with a hand brush. Residues of resin must not cure on the skin. Complete details are given in the
 material safety data sheets. All workers should be familiar with the information on these sheets.

 Highly filled formulation

 01. Fields of application
 This formulation can only be used as backup filler behind another surface, such as metal spray, polyester or
 chrome electroform. Due to the high aluminium content the heat conductivity, compared to other resin
 moulds, is better. Polyurethane reaction injection moulding (RIM), integral skin foam, flexible foam, micro
 cellular foam, rigid foam, reinforced reaction injection moulding (SRIM), fibre reinforced plastic (FRP), resin
 injection moulding, cold and hot press moulding, open mould laminating, hand lay up, prototype moulds,
 compression moulding, blow moulding.

 Advantages:
 More than 2000 kg can be poured in less than 45 minutes and can be demoulded 20 minutes after resin
 sets, back side can be machined an hour later, second half can be poured following day. Accurate
 dimensions, extreme low shrinkage, low coefficient of thermal expansion, excellent stability under heat,
 excellent temperature control, copper lines correctly used will keep surface temperature within few degree
 range, chemically bonds to it self, large pours can be done on successive days, post cure not required
 compressive strength is doubled by a post cure, but normally this is achieved during production. Easily
 machine able, tension free moulds, excellent chemical bond to polyester Gelcoat.

 Pot life at 21° C                                                        ca. 45 min.

 03. Pattern and its pre-treatment
 Ensure that there are no undercuts. Make sure the surface is smooth and clean. Prepare the pattern and
 mould box walls of materials with comparable thermal conductivity. Use stable materials to ensure
 dimensional accuracy of the mould. Coat porous and absorbent surfaces with ALWA Acrylic sealer, I.-No.
 9535, or a similar product. Apply surface tension remover, I.-No. 9500 and let it dry. Apply release
 lacquer, I.-No. 9510 (polyvinyl alcohol) and allow to dry well.

 04. Gelcoat (metal shell)
 Spray metal – for RIM and other urethane tools. Thickness of 1 – 3 mm zinc should be sprayed onto the pre-
 treated pattern. Spraying or brushing a thin polyester tooling gel coat onto the metal before backing with
 ALWA-MOULD D/ATLAS M 130 will increase bonding strength. Polyester Gelcoat – for RTM and other
 urethane tools, compression moulds. Thickness of 1 – 3 mm should be sprayed onto the pre-pattern. Avoid
 heat build-up which causes crazing of surface. After several hours, ALWA-MOULD D/ATLAS M 130 is
 poured directly onto this coat. No glass should be used. An excellent chemical bond between the polyester
 and ALWA-MOULD D/ATLAS M 130 exists. Nickel electroform – for RTM and RIM tools. Electroform must
 be high quality and without stresses for a suitable tool. Attachments to achieve a mechanical bond should
 be included on the back of the shell. The surface to be backed with ALWA-MOULD D/ATLAS M 130 should
 be thoroughly cleaned with a solvent wipe which leaves no residue before casting begins.

 05. Calculation of the preparation quantity
 1.)    Calculate the volume in litre.
 2.)    Multiple the volume in litre with the weight of the mixture = quantity of the mixture in kg.

        For example: Aluminium back filling            10 Litre Volume                    10 l x 2,4 kg = 24 kg mixture
        For example: Mineral back filling              10 Litre Volume                    10 l x 2,0 kg = 20 kg mixture

 06. Preparation of the back filler mixture
 Important: The fillers must have a temperature of 17 – 21° C!! Larger volumes mix in a concrete mixer!

 06. Preparation of the back filler mixture
 Pour all next mixtures into the first in all areas. Pure resin comes to the back surface of the casting. Fill
 now the dry granules which are reserved from the first mixture. There will not be any exothermic
 expansion. After curing (highest reaction temperature 60° C - 70° C) clamp both mould halves to each
 other and demoulded when the mould is cooled down to room temperature. Since the exothermic of the
 highly filled formulation (15/85) is much lower, a post cure of 2 hours at 80° C is recommended (longer for
 larger moulds) to increase the mechanical properties of the moulds.

 Handling precaution / Notice

 Handling precaution

 Caution!
 Our products are generally quite harmless to handle provided that certain precautions normally taken
 when handling chemicals are observed. The uncured materials must not, for instance, be allowed to come
 into contact with foodstuffs or food utensils, and measures should be taken to prevent the uncured
 materials from having skin contact, since people with particularly sensitive skin may be affected. The
 wearing of suitable rubber or plastic gloves will normally be necessary; likewise the use of eye protection.
 The skin should be thoroughly cleaned at the end of each working period by washing with soap and warm
 water. The use of solvents is to be avoided. Disposable paper - not cloth towels - should be used to dry
 the skin. Adequate ventilation of the working area is recommended. These precautions are described in
 greater detail in the Material Safety Data sheets for the individual products and should be referred to for
 more information.
