29 Based upon a three-phase molding sequence featuring prefill, shoot, and squeeze, the HANSBERG Molding System is a consolidated, foundry-proven mold making technology which ensures the production of castings consistently complying with the strictest quality control requirements. Shoot Squeeze Prefill New Moulding Line Details: Moulding Process

30 Prefill ensures that clot-free sand always fill deep pockets and cavities, even when the pattern contour is most intricate, as is the case with this knuckle arm mold Outstanding casting skin quality PHASE 1 - PREFILL

31 Shooting is instrumental to achieving high compaction in deep cavities where squeezing alone can not always reach Mold hardness 87-92° Excellent mold surface hardness with homogeneous distribution from mold center to flask edges PHASE 2 - SHOOT Distance to edge 25 mm or Less Draft Angle 0.5 Deg.

32 Outstanding mold rigidity is always achieved Minimum casting mass variation Uniform compaction throughout the mold depth PHASE 3 - SQUEEZE Minimum usage of sand Strictly controlled compression force per mold surface unit

33 FLASK DESIGN Nodular iron flask pair (above). Note the double-wall design combining high rigidity with lightness. Pin / bushing assembly (right). Each flask is fitted with one round and one elongated bushing. Poka-Yoke: Automated sensors to ensure the dimensional accuracies of pins & bushes. Pin / bushing assembly (right).

34 Flask rigidity is of paramount importance in high- pressure molding. Wall deformation should not exceed 0.25 mm under a load of 4 kg f /cm 2.

35 SPECIAL FEATURES Automatic sprue cutting unit (right). Online Automatic Sprue Cutting as compared to Manual cutting in Present Line, avoiding variation in pouring cup size Flask cleaning unit (left). Automatic Box Cleaning as compared to Manual Cleaning in the Present Line

50 HIGH PRESSURE MOLDING PROCESS We, at SPM have opted for High pressure molding process with green sand having a composition of Silica sand with 98% minimum silica content, sodium based Bentonite for better swelling and binding property, Lustrous carbon for providing a reducing atmosphere in the mold cavity. Water is added to get the optimum properties in the sand mix like compactibility, green compressive strength, Loss on ignition, dry strength, and also better collapsibility for easy separation of casting from sand at the time of knock out. This sand is reusable by remixing small quantities of Bentonite and other additives for replenishing the lost properties due to molten liquid metal casting process. Casting Technology

51 The molds for any casting component are normally made in two halves, i.e. drag half and cope half and the core for creating the inner surface of the casting component is made separately with a different process. For making both mold halves we make pattern which is mounted on match plates with respect to the center lines of the guide pins and bushes to suit to the molding machine which we are using. The pattern mounted on the match plate is incorporated with running system with in-gates for the uniform filling of liquid metal in the cavity. Casting Technology

52 In the molding process we create an outer surface of the component which we intend to manufacture and after making the mold we place the shell cores in the sand mould and this makes the internal cavities of the casting component. Casting Technology

53 Cores are set in the drag mould with respect to the core prints. In the cope mould, adequate venting is provided. Both the halves are cleaned with compressed air for any foreign particles adhering to the cavity surfaces. Then the cope half is closed on top of the drag half with the help of guide pins and bushes to avoid mismatch in the casting component. These molds are being filled with molten metal with specified chemistry and metal temperature, which helps in filling the entire mold cavities irrespective of the casting thickness variation. Casting Technology

54 The poured molds are allowed to cool on the molding line for a minimum of 45 minutes and then the castings are separated from the molds, cleaned for adhering sand particles by shot blasting, separated from the gating system with the help of breaker units and then the extra flashes, if any, are removed from the casting with the help of fettling equipments. Then the casting components are machined to remove the extra material provided as machining allowance to make the casting components suitable for assembling on other parts. Casting Technology
