[description of issuer]

1、 Combined with the situation of the company’s purchase of houses in 2021 for the capacity construction of new business of precision parts in special fields, explain the current situation of the business, the details of cumulative investment, amount, future planning and its relationship with existing business

(I) development context of precision parts business in special field and its relationship with existing business

Stage business development context, main products and Revenue Formation

Since 2013, the company has relied on independent research and development in the early stage and “02

The main products of precision machinery manufacturing and surface treatment formed by “major projects” are special field structures. From 2013 to 2019, special processes, welding and other processes began to expand products with good parts and components. Realize the market prospect of precision parts in the special field and high value-added precision parts in the special field. During this period, the overall business income was dense, and the parts were small batch business. The company’s parts and components products in this field have passed customer E and low. In addition to undertaking sales in 2016 and 2017, the company has completed the certification of special lead customer F and other customers, formed small batch sales, gradually handled the special domain qualification of customer e related structural parts, and accumulated relevant process experience. In addition, other annual incomes are basically considered to enter the special fields with higher added value, and the parts are received within 2 million yuan.

Domain, the company handled relevant special procedures from 2017 to 2019

Field qualification, preliminary necessary qualification.

With the policy promotion and the national “14th five year plan”, customers

B and other large-scale state-owned special-purpose manufacturers have limited production capacity, their products turn to higher value-added special-purpose manufacturers, and begin to cultivate qualified suppliers to provide supporting production capacity. The company participates in the field of spare parts, and also actively expands the first product development project of a certain product with customer B from 2020 to 2021. Through the exhibition, other special field products. After entering a series of processes such as process scheme review, first article processing, delivery and evaluation of products with higher added value, in 2020 and 2021, the company participated in the precision parts business of customer B in 2020, received parts in the field of production bidding, and began to supply specific models of products after winning the bid. With the deepening of cooperation with customer B, the precision in the special field is 202844 million yuan, accounting for the first article certification of parts in each phase and the variety of mass production products are increasing. The proportion of industry revenue is less than 3%. Compared with the end of 2020, the company has been selected as the leading unit of customer B “a certain production and application business has begun to enter the high-speed growth product specialization strategic supplier cultivation project”.

Through one-year feasibility demonstration and preliminary preparation, December 2021

Shenyang Qiangqiang company and other investors jointly set up a new subsidiary in June

Aviation, undertake the product production and processing industry in the special field of customer B

Business.

In addition, the company also actively expands its business in other special fields,

Relevant products have passed the certification of customers in corresponding special fields.

(II) investment in precision parts business in special fields

1. Investment of original plant

The company has not yet entered the customer B supplier system in the early stage, and there is less demand for products. The company mainly uses the original Shenyang plant located at No. 18, Feiyun Road, Hunnan District, Shenyang, the rented plant located at No. 18-10, Changqing South Street, Hunnan District, Shenyang (expired at the end of October 2021 and not renewed) and a small amount of special equipment for the production of corresponding products. As the company won the bid for customer B product in 2020, the corresponding business demand has increased rapidly, and the original plant capacity has been seriously insufficient.

2. Investment of new plant in Shenyang

Shenyang new plant, located at No. 22, Feiyun Road, Hunnan District, Shenyang, will be used as the production base of precision parts in the company’s special field (not involving a specific part product in the special field) (the special equipment of the original plant is planned to be moved into the new plant, and the new plant also includes the production capacity of precision parts of semiconductor equipment). By the end of 2021, the new plant in Shenyang had been converted to fixed assets, and some machinery and equipment had not arrived or completed installation and commissioning, as follows:
