What Merapi does

CV Merapi is an Indonesian full-service grey iron foundry established in 1993 in Boja, Kendal (Central Java), operating a single integrated manufacturing complex that spans pattern preparation, greensand casting, in-house resin-coated sand (RCS) core production, melting/pouring with temperature control, cleaning/trimming, CNC machining, and coating/finishing. The company produces castings in FC200 and FC250 grades at a stated capacity of 500+ tons per month, with a workforce of 400+ employees. Its product portfolio spans five lines: Sun Rise commercial gas stoves (SNI 7613:2019 certified), Sun Rise cast iron cookware (BPOM No.20/2019 food-safety approved seasoning coating), Merapi plumbing fittings (clamp saddles, gibault joints, roof drains, manhole covers), SR Autoparts (cylinder liners, valve guides, valve seats for motorcycle engine overhaul), and SR Resin Coated Sand sold to external foundries in three standard grades plus custom formulations.

The company operates three concurrent go-to-market models: OEM (producing castings to client designs and specifications), ODM (rebranding from a 300+ SKU catalog under the client's brand), and OBM (distributing own Sun Rise, SR Autoparts, and SR RCS brands through an active distributor network covering more than 30 Indonesian provinces, with export activity into ASEAN and EU markets). Revenue is generated primarily through hardware sales across all branded product lines plus manufacturing service fees for OEM/ODM contracts; pricing is quote-based and not publicly disclosed. The customer base is horizontally diversified across four distinct end-markets — Horeka/hospitality, UMKM culinary, automotive aftermarket, and construction infrastructure — reducing dependency on any single vertical. Certification footprint (ISO 9001:2015, SNI 7613:2019, TKDN domestic content, BPOM food safety) positions the company for both export and Indonesian government procurement opportunities.

The business is privately held and founder-controlled, with no disclosed external investors, funding rounds, or M&A activity in the source material. All manufacturing is concentrated at the single Kendal facility; the company website, social channels, and product catalogs remain active and updated, indicating ongoing operations. Privacy policy revision in June 2026 suggests continued corporate governance attention to data protection compliance under Indonesia's UU PDP framework.

Broad incumbents

• Staub (Zwilling): Premium cast iron cookware brand owned by Zwilling J.A. Henckels. Competes in the same premium cast iron segment as Sun Rise cookware in international markets.
• Höganäs AB: Swedish global leader in metal powders and iron-based products for foundry and metallurgical applications. Comparable as a global foundry materials and iron-processing specialist relevant to Merapi's RCS and casting operations.
• Le Creuset: Global premium cast iron cookware brand. While Le Creuset outsources most production, it competes head-to-head with Sun Rise cookware in the cast iron category and represents the upper bound of brand-led cast iron economics.
• Waupaca Foundry: One of the largest iron foundries in the US producing grey and ductile iron castings for automotive, construction, and industrial markets. Comparable as a large-scale iron foundry serving diversified OEM customers.
• Rinnai Corporation: Global manufacturer of gas stoves and commercial cooking equipment. Comparable as the broader incumbent competing with Sun Rise commercial gas stoves in Indonesia and ASEAN markets.

Emerging players

• Smithey Ironware: US-based cast iron cookware brand with a smaller-scale, branded foundry model. Comparable as an emerging cast iron cookware brand building premium positioning — parallel to where Sun Rise could go internationally.
• Field Company: Niche US cast iron cookware brand focused on lighter, vintage-style skillets. Comparable as a small-scale, branded cast iron player targeting premium consumer segments — relevant for benchmarking Sun Rise brand strategy.

Direct peers

• Lodge Manufacturing Company: The largest US cast iron cookware foundry operating a similar OEM-plus-owned-brand model. Lodge produces grey iron castings and finished cookware (skillet, Dutch ovens) — directly comparable to Merapi's cast iron cookware and foundry operations.

Regional players

• PT. Krakatau Steel: Indonesia's largest steel producer. Adjacent comparison as a large Indonesian metal manufacturer whose customers (foundries, fabricators) overlap with Merapi's downstream markets; relevant for understanding domestic metal supply dynamics.
• PT. Surya Metalindo Perkasa: Indonesian metal casting and fabrication company producing cast iron products for domestic and export markets. Direct regional peer competing in the same Indonesian foundry and iron casting market.
