Automotive NTC assembly line for Single-End Automotive NTC Line

Project scope

We designed a single-end automotive NTC production line around product samples, an end-to-end process layout, tooling, carts, encapsulation frames, testing and optional semi-automatic test equipment. That makes the scope an Automotive NTC assembly line application for single-end automotive sensor production line.

Production objective

We built the design around a daily output target of about 8,000 pieces in a 10-hour shift. It describes the full route from boarding and welding through encapsulation, shell potting, sealing-ring assembly and temperature-based resistance testing.

Hybrid line design

This is not a lights-out line. We combine automated boarding and welding with manual line insertion, multi-stage encapsulation, baking and parts handling. The challenge is to keep the hybrid flow stable without over-investing for an 8,000-piece daily volume.

Automotive-style test requirements

The line includes resistance testing at both 25 C and 85 C, plus data collection. That pushes the process closer to automotive validation logic than a simple room-temperature bench check.

Tooling and recirculation

We devoted several pages to line boards, encapsulation fixtures, shell-potting fixtures and turnover carts. That indicates fixture recirculation was a major design factor for this product family.

Front-end and encapsulation

The plan starts with automatic wire cutting and boarding, then single-end welding. We rated the boarding machine around 1,800 to 2,000 pieces per hour and the single-end dual-machine welding section around 800 to 1,000 pieces per hour.

Turnover and baking support

For the stated daily volume, we planned four turnover carts and 120 encapsulation frames, plus dedicated oven support. We also broke out the tooling budget for line boards and shell-potting fixtures.

Testing architecture

The testing section includes both empty-state and constant-temperature testing, using 25 C and 85 C water-bath logic plus data capture. We also discuss an optional semi-automatic tester that is not included in the base budget.

Key technical parameters

Area	Configuration	Planning value
Daily target	Single-end automotive NTC line	8,000 pcs per 10-hour shift
Boarding	One cutting and boarding machine	1,800 to 2,000 pcs/hour
Welding	Single-end dual-machine welding section	800 to 1,000 pcs/hour
Turnover	Carts and encapsulation frames	Four turnover carts, 120 frames
Oven support	Floor-push oven arrangement	Two ovens in the working concept
Fixture set	Board, encapsulation and shell-potting fixtures	Sized for fixture recirculation
Testing	25 C and 85 C resistance testing plus data capture	Manual loading with automated collection
Staffing assumption	Human-machine combined line	About 15 people including management and quality roles

Business arrangement

The planning model is based on no less than three million parts per year, a five-year production commitment and a processing-fee logic of CNY 0.40 per part. The investment scenarios show a human-machine combined equipment package in the CNY 218,350 to CNY 222,500 range, with a later option to continue cooperation or transfer the equipment after the initial term.

Proposed operating result

The result is a hybrid automotive NTC line that deliberately balances automation with manual handling where we judged it more practical. It is sized for moderate daily volume rather than maximum automation density.

Business planning value

The design includes line capacity, labor context, fixture quantities, testing options and commercial deployment assumptions. That gives the customer a usable roadmap for staged deployment instead of only a concept sketch.
