Shengquan Group Foundry Resins, Coatings, Filters and Riser Sleeves

Selection and quotation of Shengquan Group foundry materials: SQG and F-200 furan resins, GP and ZL cold box resins, inorganic binders, FQ and FS coatings, FCF filters and FT sleeves.

SQG, SQM and F-200 Furan Resins for No-Bake

Furan resins for no-bake sand: high strength SQG, lignin-based SQM, a resin for 3D printed moulds and low VOC F-200. According to the manufacturer, curing releases 30-50% less formaldehyde, and hardener addition drops by 10-20% at the same bench life.

Furan resin output: 150,000 tons per year
First furan resin released in 1987
Formaldehyde emission during curing down 30-50%
Hardener addition reduced by 10-20%

GP and ZL Cold Box Resins and FR Hot Box Resin

Resins for the amine cold box process: eco-friendly high strength GP, high strength low viscosity ZL and a sulfur dioxide cured grade. The maker aims them at mass core making for automobiles, tractors and engines. For heated core boxes there is the heat-curable FR resin.

Cold box resins in the range since 1996
GP: high core strength
ZL: low viscosity sand mix
FR: fast curing in a hot box

Alkaline Phenolic and Phenolic Urethane Resins

Alkaline phenolic resins for the α-set process with an organic ester hardener: JF-103A and eco-friendly JF-200H. For the β-set process hardened by CO2 gassing there are low smell SQJ610 and JQ-100. NP and ZF phenolic urethane no-bake systems combine resin, polyisocyanate and catalyst.

Alkaline phenolic resin since 1991
α-set: ester curing at ambient temperature
β-set: hardening by CO2 gassing
NP system: no sulfur or phosphorus

FW and SWT Warm Box Binders, ZW Inorganic Binders

The FW organic warm box system of furan resin, curing agent and additive targets cores for aluminium parts. The SWT inorganic warm box binder is a silicate system of a liquid binder and powder additives. ZW102, ZW106 and ZW200 inorganic no-bake binders serve steel foundries.

FW: three-component system
SWT: liquid binder plus powder additives
ZW106: humidity-resistant grade
ZW200: fast curing grade

EPC, SQM, FQ and FS Foundry Coatings

Coatings are applied to sand, metal, foam and plastic moulds: during pouring the layer separates molten metal from the mould and improves the surface of the part. The range covers EPC lost foam coating, SQM metallic coating, FQ alcohol-based and FS water-based grades.

Foundry coatings since 1994
FQ: alcohol-based coating
FS: water-based coating
EPC: lost foam coating

FCF, CHF and BXF Ceramic Filters

Filters clean the melt and improve the surface and internal quality of the part. The range covers FCF foam ceramic filters for steel, iron and non-ferrous alloys, CHF pressed filters, a double layer composite filter and BXF fiber filters. They are exported to over 40 countries.

Foam ceramic filters since 1999
FCF: steel, iron and non-ferrous alloys
Double layer composite filter
BXF: fiber filter

FT, FM, FI and L7 Riser Sleeves

The exothermic agent ignites on contact with molten metal and releases heat while the sleeve wall insulates it, so solidification in the riser takes longer and a smaller riser can feed the part. The range covers FT and FM exothermic-insulating, FI insulation and L7 high strength sleeves.

Exothermic-insulating risers since 2007
FT and FM: exothermic-insulating series
FI: insulation riser series
L7: high strength riser series

Choosing a Binder by Process and Alloy

SQG, SQM and F-200 furan resins and NP and ZF phenolic urethane systems serve no-bake moulds and cores for steel, iron and non-ferrous alloys.

Alkaline phenolic resin in the α-set process cures with an organic ester at ambient temperature and, as the maker states, helps against cracks; in the β-set process the sand hardens by CO2 gassing. GP and ZL cold box resins and FR hot box resin target mass core making.

For aluminium the maker lists FW organic warm box resin and SWT inorganic binder, for steel the ZW inorganic no-bake binders.

Choosing a Coating by Mould Type and Carrier

Coatings are applied to sand, metal, foam and plastic moulds. For lost foam work the range offers EPC, for metal moulds SQM metallic coating, for sand moulds alcohol-based FQ and water-based FS.

The maker lists the coating properties: thixotropy and levelling with no brush traces, good suspension stability, low gas emission against blowholes, high refractoriness and a clean finish surface.

Filters and Riser Sleeves in the Gating and Feeding System

FCF foam ceramic filters are chosen by alloy: steel, iron or non-ferrous. The range also includes CHF pressed filters, a double layer composite filter and BXF fiber filters. The filters keep strength at room and high temperature and offer high porosity and large filtration capacity.

Sleeves are chosen by feeding task: FT and FM exothermic-insulating sleeves generate and hold heat, FI insulation sleeves only hold heat, and L7 sleeves are high strength.

Grade Check and Batch Quotation

For selection we check the process (no-bake, cold box, hot box, warm box, α-set or β-set), the alloy, the core or mould type and the system make-up: resin, hardener, catalyst or additive. Multi-part systems such as NP and ZF phenolic urethane or FW warm box are ordered as a set of parts.

The maker offers technical support in product development, application and process optimization; grade and batch are agreed on its technical data.
