Founding - Equipment for the production of lost patterns for the lost wax casting process

This standard specifies the requirements for tooling for the production of lost patterns for the lost wax process including soluble wax cores, and the production of ceramic cores. This standard does not specify equipment used to produce castings by the Shaw process. This standard does not specify the processes which directly generate the lost pattern(s) by means of numerical data such as stereolithography or sintered wax process or laminated object manufacturing (LOM).

Gießereiwesen - Einrichtungen zur Herstellung von verlorenen Modellen für das Wachsausschmelzverfahren

Diese Norm legt Anforderungen an Formwerkzeuge zur Herstellung von verlorenen Modellen für das Wachsausschmelzverfahren einschließlich löslicher Wachskerne und die Anfertigung von keramischen Kernen fest. Diese Norm enthält keine Festlegungen für Einrichtungen zur Herstellung von Gußstücken nach dem Shaw-Verfahren. Verfahren, nach denen das oder die verlorenen Modelle direkt nach zahlenmäßigen Angaben, wie z.B. Stereolitho- graphie, Sinterwachsverfahren oder Laminierverfahren (LOM), angefertigt werden, sind in dieser Norm nicht festgelegt.

Fonderie - Outillages pour la production de modeles perdus pour le procédé de moulage a la cire perdue

La présente norme européenne spécifie les exigences de l'outillage pour la fabrication de modèles perdus pour le procédé à la cire perdue, y compris des noyaux de cire soluble, ainsi que la fabrication de noyaux en céramique. La présente norme ne spécifie pas l'équipement utilisé pour produire des pièces moulées par le procédé Shaw. La présente norme ne spécifie pas les procédés qui génèrent directement les modèles perdus au moyen de données numériques tels que la stéréo-lithographie, le procédé à la cire grésée ou la fabrication d'objets stratifiés.

Overview

EN 12883:2000 is a CEN standard that specifies requirements for tooling used in the production of lost patterns for the lost wax (investment) casting process. It covers tooling for manufacture of lost patterns - including soluble wax cores - and tooling for the production of ceramic cores. The standard explicitly excludes equipment for the Shaw process and does not apply to pattern-generating processes that use numerical data such as stereolithography, sintered wax, or laminated object manufacturing (LOM).

Key topics and requirements

This standard focuses on requirements relevant to tooling for lost pattern production, including:

• Tooling scope: Requirements for tooling used to produce wax patterns and cores intended for the lost wax casting route.
• Soluble wax cores: Tooling requirements that address production of soluble wax core elements used in coremaking.
• Ceramic core production: Tooling used in the manufacture of ceramic cores for investment casting.
• Exclusions: Clear exclusions for Shaw-process equipment and additive or NC-based pattern generation (stereolithography, sintered wax, LOM).
• Identification of industry context via ICS codes (e.g., 77.180 – Equipment for the metallurgical industry; 25.120.30 – Moulding equipment).

Note: EN 12883:2000 defines what types of equipment/tooling are covered and what is excluded; it does not detail processes that create lost patterns directly from numerical data.

Applications

EN 12883:2000 is intended to support consistent specification and use of tooling in industries that rely on lost wax casting. Practical applications include:

• Developing procurement specifications for founding equipment and tooling.
• Guiding tooling manufacturers on scope and compliance expectations for wax and ceramic-core tooling.
• Assisting foundry engineers and production planners to select appropriate tooling for wax pattern and core manufacture.
• Supporting quality and conformity assessments for equipment used in investment casting workflows.

Who uses this standard

• Foundries and investment-casting shops
• Tooling and mould manufacturers for wax and ceramic cores
• Equipment suppliers and purchasers in the metallurgical industry
• Quality managers, production engineers, and procurement specialists concerned with tooling compliance

Related standards

EN 12883:2000 sits alongside other CEN and industry standards covering casting processes, safety, and metallurgical equipment. When specifying equipment, users commonly reference this standard together with relevant casting and materials standards to ensure complete compliance and interoperability.
