State of the art and highly reliable production machines For in-house production of components, Perucchini uses the most advanced machines able to perform high productivity and capability and to grant high quality standards. Perucchini has been cooperating for several years with the leading manufacturers of foundry equipments ( Mec-Ind, Euromac, SLS). Main features of the most important plants:

• Automized pouring robot • Automized finishing lines • Last generation medium frequency furnaces • Semiautomatic shells making machines • Heat treatment fournace

3 Purpose of the Standard Quality Plan This Quality Plan, edited in conformity to UNI ISO 10005 norm, shows the procedures carried out by Perucchini to comply with the quality requirements applied to the production of castings. The document has been deliberately issued in synthetic form and with general purpose contents because specific information are just included in the Quality Manual. Perucchini operates on customers commission. The operative modalities are described in the Quality Plan. If the contents of this document do not comply with the customers requirements, a registered copy of the Quality Manual could be required to the Perucchini Quality Assurance Service. This document is considered under “not controlled distribution”. 4 Perucchini and Quality Assurance Perucchini operates in accordance with a Quality System conforming to the UNI EN ISO 9001:2015 norm. This certification has been achieved in year 1998 by IGQ (Istituto Italiano Garanzia Qualità) certification body, through the issuing of the certificates no. 9829 and IT-5378. The next renewals have been achieved by IGQ until year 2008; starting from 2009 the renewals have been achieved by CSQ with certificates no. 9190.PRCC and IT-68433. The research of the continuous quality improvement of the castings supplied to its customers, lead the company to apply, to the current quality system, the basics of the IATF 16949 standards, with the target of obtaining the certification.

6 Checking of documents, data and records All Perucchini documentation is identified, registered, protected and preserved in accordance with qualified criteria conforming to UNI EN ISO 9001:2015 norm. All internal documentation is managed through specific procedures and specifications that define modes and responsibilities for their processing, coding, distribution and review. The responsibility of the external documentation management falls on the reference department who is in charge of the specific activities of management, registration and distribution. The external documents (norms, technical specifications of the customer) are registered in special lists drew up and updated periodically by QA dept. The data management is carried out by Perucchini both on paper and on data processing supports according to the running software used for management, design and usual practice and handled by the IT dept. The records are identifiable, traceable and preserved for a minimum of three years. The Quality reporting will not be disclosed to entities outside the company except for specific agreement with the end customer during the "contract review". The documentation management is instead different in case of IATF, since all what concerns the products of the Automotive sector (registrations specified by the Customer included), must be filled for the product entire life plus one calendar year, if not differently specified by the Customer, and anyhow not less than 5 years (except different binding applicable dispositions). The quality documentations are divulged as per what aside illustrated. Quality reference documents: I-33-ASQ, I-37-ASQ

7 Training Staff training is handled at all company levels according to defined procedures and skills required for specific roles or functions. QA dept is responsible for the program management, training and refresh courses. Quality reference documents: P-06-DGE

8 Order processing and customer service All customer notes, specifications and purchase orders are analyzed and checked in the definition of the product requisites. Commercial (MRKT), technical support-to-sales (ITEC) and technical dept. (TEC) are responsible for analysis and development of technical-commercial inquiries. Quality reference documents: P-04-DGE, I-38-ASQ

9 Research & Development By project it is meant the elaboration, the analysis and the manufacturing of the toolings as well as the castings production. The products design is developed by two different services: technical office that is the responsible for components design; R&D that is responsible for procedures testing and products validation. The “Project” worked out by the technical dept. is approved by Marketing Dept. and General Management. The control and the validation of the project are carried out by submitting samples, representative of the series supply conditions, to the customer. Quality reference document: P-04-DGE

10 Outsourcing and suppliers management In order to maintain high quality rating of purchased components, Perucchini makes use of suppliers with quality system according to UNI EN ISO 9001:2015 or IATF 16949 or with own quality system aligned to ISO standard. Each supplier is qualified and constantly monitored through specific audits carried out by Perucchini QA and Purchase dept. specialists. The Suppliers Vendor Rating (VR) is issued every six months, in order to monitor suppliers performances in terms of quality of supplying, reliability of delivery terms, flexibility and technical support forwarded to Perucchini, purchase price. Suppliers with underperforming VR index respect to Perucchini fixed target are called to jointly define proper countermeasures to restore the required quality rating. The PAP procedure (Product Approval Process), derived from Automotive PPAP, is also active for the verification and validation of products manufactured by new suppliers or by already approved suppliers in

Standard Quality Plan

case of changes in their production process; with the achievement of the IATF certification, the procedure will be integrated and updated so as to fully follow the PPAP procedure. The purchase orders are formalized on specific numbered forms, including the contract terms fixed in the relevant supplier’s contracts. Quality reference documents: P-05-DGE

11 Production The internal and external productions are managed through manufacturing and inspection cycles, worked out for all types of products according to defined procedures. The process management and control are directly carried out by the involved operative personnel according to procedural Control Plans integrated with proper Operating and Visual Instructions. In section 18 flow charts of the standard production process of Perucchini are reported. Quality reference document: I-38-ASQ

12 Identification and traceability Perucchini keeps under control and records the unambiguous identification of the product by the assignment of an internal code also mentioned on the manufacturing tooling as well as on the correlated documents. The traceability is essentially based on two data: - Foundry Code - Production Batch (corresponding to the number of our internal job order) Them both are indicated on all the documentation concerning each specific casting. This makes it possible, starting from the production batch mentioned on the QUALITY CERTIFICATE issued after the final checking, to get back in the production process up to the shells making. If contractually requested by the Customer, the casting can be marked by cold imprinting on the part directly, or by a clock date stamp introduced in the tooling (cavity) so as to make the traceability more prompt. Quality reference document: I-35-ASQ

13 Control of goods owned by the customer Shell-Moulding tooling: The toolings for the shells and the cores making are customer owned and are univocally identified. They are kept in appropriate stocks from which they are taken when the production has to be carried out. At the end of the production process, and before being put in the stocks again, they are carefully cleaned up and subjected to a quality check. Final check tooling: When required by the project, the dimensional control gauges or the coining and shearing tools customer owned, are kept in appropriate stocks from which they are taken when needed for the operations indicated in the technical specifications of the project. At the end of each production cycle they are carefully checked so as to verify their wear condition and the respect of the tolerances required by the project. Quality reference documents: I-29-PRO, I-35-ASQ

14 Products preservation All the parts managed in the company are handled, stocked and preserved so as to conserve their quality and characteristics. The castings are usually packed in metallic boxes owned by Perucchini, to be returned, except different contractual agreements taken with the Customer. Quality reference document: I-10-PRO

15 Checking of not conform products Specific areas for the segregation of nonconforming products are well marked in all production departments. The products nonconformities are always identified with coloured tags: red for material to be rejected; yellow for material to be checked and overhauled. The rejected product is quickly scrapped or returned to the supplier in order to prevent any possible misuse. The exceptionally accepted or repaired material is properly identified and managed to allow its traceability in any phase of production process. The analysis of nonconformities is handled through the Problem Solving methodology. The non-conformities procedures can be issued by any company dept. and they are always registered on QUARTA software according to defined procedures. QA dept. determines the method to manage the nonconformity and the activities needed to analyze the problem, the service in charge of the analysis and the action planning to prevent future occurrence. Quality reference document: I-36-ASQ

16 Monitoring and measurement Process control is an effective and objective method to detect products nonconformities. Inspections and tests are carried out on three different phases basis. Acceptance sampling is done by the acceptance control dept. according to a sampling plan. Drawings/specifics of the casting, operative and visual instructions are adopted as reference documents. The sampling results are processed through SAP-QM, a specific software also able to issue effective and precise survey. On line controls performed by the production personnel based on control plans; they are supervised by the foreman and the Quality Control. On line controls are registered on specific department registers or via acquisition data software. Design drawings and manufacturing operational charts are used for such a purpose. Final tests are performed on all components by the testing operator and in accordance with the product test specification and with the Visual Instructions. The objective proof of the functional tests execution is granted by the presence of id labels. All the instruments used to control and test components are encoded and registered on specific master registration cards. Their suitability is constantly verified by the QA personnel employed in metrological laboratory through the relevant controls established in the same master registration cards. The instruments verifications are carried out by using primary samples SIT or by relying on external accredited laboratories. Quality reference documents: P-05-DGE, I-38-ASQ, I-03-ASQ 17 Audits, statistic survey, corrective and preventive actions Quality audits are constantly carried out by the QA personnel both inside the Company structure and organisation as well as at the external suppliers. The results of the inspections are always registered on specific forms, that are integral part of the Quality system documentation. Statistical techniques are applied to constantly monitor the performances of the most significant indexes: - External nonconformities reported by customers - Internal nonconformities reported by departments or in-house - Nonconformities dependent on outsourcers and detected in acceptance - Controls and tests in acceptance and in production - Products’ overhauling - Customers claims - Delivery delays Quarterly the QA dept. draws up the non-conformity analysis in accordance with defined procedures. In order to raise awareness and involve personnel at any company levels, quarterly the survey charts of the most significant quality indexes are displayed in the relevant showcases present in all production areas. Corrective and preventive actions come out from the analysis of product or service nonconformities that are registered through internal and external nonconformity claims as well as from audits carried out by the Notified Body. The accomplishment and effectiveness of the engaged corrective action is planned and monitored in subsequent audits. Quality reference documents: I-14-ASQ
