Made-in-China listings pulled on 2026-06-29 put Quanzhou Sanjia Machinery's hot-box core shooter alongside Goldsupplier peers' Top-Class hot-box/cold-box foundry sand core shooter machines, with both carrying ISO 9001 and CE approval language on the supplier cards [S1][S5]. The category sits inside the Metal Casting Machinery filter on Made-in-China, which groups shell moulding, hot-box and cold-box shooters under one buyer-facing taxonomy [S6].
Order prices in this category span roughly US$10,000 to US$80,000 FOB China for a single station, with a working MOQ of one set; the spread is set by head count, maximum shot weight, platen heating power, and whether the unit is sold as a hot-box-only machine or as a hot-box/cold-box convertible [S5][S6].
Price Bands the 2026 Market Actually Quotes
Quanzhou Sanjia's hot-box core shooter sits in Made-in-China's Metal Casting Machinery category, where Sanjia self-describes as Manufacturing & Processing Machinery and lists the hot-box unit with an automatic double-head core shooting configuration [S1]. On the same platform, Goldsupplier-marketed Top-Class hot-box/cold-box foundry sand core shooter machines are flagged with ISO 9001-2008 and CE approval text, and are sold against the same buyer pool [S5]. The Made-in-China "shooter price" aggregate filter shows 11,515 listed products in mid-2024, with the Metal Casting Machinery bucket straddling US$10,000 units at the low end and a wide ceiling for large dual-head or convertible machines [S6]. For a 2026 buyer running an RFQ, a realistic first-quote band is US$10,000-80,000 FOB for a single station, and US$120,000-200,000+ for a dual-head or hot-box/cold-box convertible line, with shipping, tooling and a separate amine/phenolic binder dosing skid still to be added [S5][S6].
Five Spec Levers That Move the Number
First, head count: a single-head hot-box shooter sits at the bottom of the price ladder, while a dual-head automatic configuration like Sanjia's quoted unit adds a second sand magazine, second shooting head and shared controls [S1]. Second, maximum shot weight: small-job machines rated for 5-15 kg shots are common in the sub-US$20,000 tier; 25-50 kg shot weights typically push the figure into the US$40,000-80,000 range [S5][S6]. Third, platen heating: hot-box tooling is heated to roughly 200-260 °C, so the electrical cabinet, platen heater wattage and gas-exhaust hood are genuine cost items that a cold-box machine does not need - this is the single biggest hardware delta against a cold-box counterpart, which uses amine gas curing at ambient tool temperature [link to the cold-box buying guide below] [S5]. Fourth, controls level: basic relay-logic panels are standard, while PLC + HMI packages with recipe storage and shot-profile trending are a measurable option. Fifth, certification language: ISO 9001:2015 and CE markings are listed on multiple Goldsupplier cards, but the cost of CE documentation and a witnessed FAT should be priced separately from the machine base price [S5][S6].
What Hot-Box Actually Costs to Run vs Buy
A hot-box core shooter uses a thermosetting phenolic or furan binder cured in a heated core box, so the recurring consumable is the resin-coated sand plus the electricity for the platen heaters; this is the line item that separates hot-box operating cost from cold-box operating cost, where the binder is cured by amine gas at room temperature [S1][S5]. Tooling wear is a quieter cost driver: heated core boxes run hotter than cold-box tooling, so tool steel choice and any surface treatment should be specified on the RFQ, not left to default. For buyers comparing hot-box against a cold-box line on total cost of ownership, a structured side-by-side is essential - the cold box core machine entry defines the ambient-cure class on the other side of that comparison, the 2026 Cold Box Core Shooter Price & Cost Guide lines the binder chemistry, gas-handling and curing-energy side of the comparison, and the Cold Box Core Shooter 2026 Buying Guide covers the spec gates that a hot-box bidder will be asked to match.
Buyer-Fit Matrix: Who Hot-Box Is For and Who It Isn't
Hot-box is a fit for foundries running medium-to-high volumes of small-to-medium sand cores where the binder cost of a phenolic or furan system is justified by cycle time, and where the plant already handles heated tooling; iron, steel and non-ferrous jobbing shops typically fit this profile [S1][S5]. It is a poor fit for very large cores (above roughly 50 kg shot weight, where cold-box gas-curing scales more cleanly), for low-volume job shops that cannot amortise the platen-heating electrical load, and for any site that cannot accommodate the gas extraction required above a heated core box [S5]. A buyer sitting on the boundary should look at the six-spec-gate selection methodology - those gates (shot weight, cycle time, binder system, tooling interface, gas handling and controls) apply to hot-box RFQs with only the binder-system row changed.
RFQ Checklist for a 2026 Hot-Box Order
Lock the spec sheet down to: maximum shot weight in kg, cycle time in seconds, platen dimensions in mm, platen heating power in kW, head count (single vs dual), binder system (phenolic/furan), tooling interface pattern, controls package (relay, PLC, PLC + HMI), and which certifications (ISO 9001:2015, CE) the supplier must produce on FAT [S5][S6]. Confirm whether the quote is FOB, CIF or DDP, whether commissioning is included, and whether the resin-coated sand supply is on the supplier or the buyer. Insist on a written shot-weight vs cure-time curve at three platen-temperature set points; this single document catches most of the over-rated machines in the marketplace before they ship. For context on the equipment taxonomy a hot-box machine sits inside, the shell core shooter encyclopedia entry covers the related shell-process hardware, while the hot box core machine entry defines the curing class.
Two trackable signals to watch: (1) whether the Made-in-China Metal Casting Machinery category continues to cluster hot-box and cold-box shooters on the same supplier cards, which compresses bid comparison time for buyers; (2) the spread between single-head and dual-head FOB quotes, which is the cleanest read on whether the 2026 market is adding margin at the configuration step or at the certification step [S1][S5][S6].
