Resin Sand Casting aluminum core metal box
Mouth. And ends at the same time pouring molten metal in order to ensure a smooth filling; sand core is a resin from the hard sand core, gas evolution large, should be pouring liquid metal fast filling system to open. Two straight gate (25ram) {four runner (20ramX30mm); six of the gate (60mmX5mm) the entire cross-sectional area ratio of the gating system is: = Fi Summer F_l = F since 1l2.45I1. Ya 2.3 ■ mouth four that take IZl,mulberry, root diameter riser section at the diameter of the casting heat 0.9 times the riser height and diameter ratio of 25. 2.4 chilling measures on both sides before and after 40 27mm hole with a metal core formed, played a role in cold 2.5 Kam structure of iron metal to adopt a comprehensive classification,abercrombie madrid, basically constituted by the four blocks of box-type structure, with a friction-tight town town tight body, it is a good casting The mold and die manufacturing. Mold made of HT25C,franklin marshall,. Wall thickness of 3O ~ 35mm,uggs, the back of the ribs increases with the intensity of cavity surface roughness Ra6.3 ~ 3.2 Founding of the mold with a screw drive model,ralph lauren danmark, reducing the labor intensity. 2.6 steel core steel core leader of the first place is to ensure that core and accurate positioning of the steel core metal head and cast as one of the bone core, steel core head and the metal contact area open triangle exhaust ducts. Distance 50 ~ 80mm, deeply 1man. So that when filling the gas discharge cavity. 3 Resin Sand cast aluminum core temperature than cast iron, cast actinides pouring temperature is much lower. Hot sand core suffered minor role. And thin-walled aluminum alloy box casting resin self-hardening sand core production. The resin from the hard sand core of sand is very important to choose low alcohol hydrazone resin, the resin should step up to meet the technical requirements shall prevail. Resin Sand ensure a good sand core material of 3.1 (1) scrub sand (Dalin): Grades for the 90-0.3-0212AH-l154 (2) resin (FFD - 141 type); ca ) phosphoric acid (85 industrial phosphoric acid). 3.2 core sand preparation process (1) Sand equipment: $ 2o2 2t-type resin mixer bowl. (2) sand craft: A single sand double mixing method sand + phosphoric acid + sand (3) core sand composition and technological properties in Table 1, Table l resin composition from the hard sand bearing in mind technological properties of garlic 3.3 Resin Sand core with WGch - 2. Paint coating B0. 4 4.1 Gold ■ type casting process to prepare before pouring,billiga uggs, the metal preheated to 200 The remaining water. Until the paint dried before use. 4.2 sand core temperature: 20 ~ 40 ℃; 4.3 box-type work ju ■ degree: 250 ~ 300 casting, and strive to ladle cup near the gate, so that the steady flow of liquid metal, so that the first slow,mulberry norge, then fast,franklin marshall sale, then slow. Finally, liquid-poured metal riser. (Editor: Yuan Zhenguo) (-t pick No. 46) Laempe gas generator with a large capacity of the heater, thereby virtually eliminating the above problems, and uses quantitative techniques to obtain the plot pits a precise quantification. Programmable Logic Controller (PLC) and computer control of the program also allows users to pre combination of quantitative and quantitative control after blowing quality. Xinjiang hard sand with his lU 5 store quantitative and dip before the quantitative dose-expiratory pressure and blowing catalyst can be any of the characteristics of proportional valve can ensure the realization of various characteristics of blowing pressure curve. Hardening process for each of the sand core is a continuous variable and infinite variability of the gas in order to ensure the catalyst to overcome the resistance of the sand core of sand core to the furthest point,mulberry oslo, can be used twice a hardening process. Hardened core of mussel cultivation expiratory pressure ring 6 to i mussels blowing pressure (shrinkage: Zhang summarized Bin), the firm introduced Hao Jin Lee County, strontium and aluminum alloy plant deterioration Jing strontium alloy factory to introduce the latest scientific and technological achievements,uggs kopen, using a special roasting and vacuum to restore the new technology,ugg outlet, development and production of the metal strontium and ytterbium aluminum alloy. Widely used non-ferrous alloy of aluminum and deterioration. Its performance with the traditional ternary modifier, compared with a deterioration effect, long-lasting, non-toxic, easy to use, low cost. I saw the production of plant and aluminum strontium alloy detected by Shanghai Institute of Metallurgy, reached the international standard level; users generally well received. That our products quality stable and reliable,mulberry outlet, and good technical and economic benefits. Our aim: to win the trust of excellent to clean win. Sincerely welcome new and old customers call, contact us and order the director: Hu Jin surgery Contacts: Fan Quanxing Add: Suzhou Li villa outside the town of South Postcode: 215128 Tel :0512 -552 955 Fax :0512-55789435m
