Manufacturing processes used in the spring industry
The production of metallic springs requires specialized processes that vary depending on the application and Market requirements vary.
The choice of the appropriate manufacturing process depends on the required quantity, production costs and technical requirements.
In the metal spring industry, processes such as mass production, series production, small series production, variant production and quota production are important.
In addition, there are other processes such as individual production and batch production.
Analysis of quantities, costs, examples and areas of application:
1. Mass production
Mass production is a highly automated process designed for the production of large quantities of standardized springs.
In the spring industry, this process is mainly used for standard springs that are required in large quantities.
Quantities:
Typical: 100,000 to over 1,000,000 pieces.
Examples and applications:
Automotive industry: suspension and valve springs.
Household appliances: springs for washing machines, dryers or refrigerators.
Electronics industry: spring contacts in connectors and electronic devices.
Advantages:
Low unit costs: Due to the high production volumes and the use of automated production lines, the costs per unit are reduced considerably.
High efficiency: Optimized production processes and machines enable high production speeds and consistent quality.
Fewer human errors: Automation reduces the influence of operator errors and improves Product quality.
Disadvantages:
High investment costs: The initial cost of machinery and tooling is very high.
Low flexibility: Changes to the design or specification result in high costs and delays.
Warehouse costs: Due to the large quantities, storage capacity must be planned, which can lead to additional costs.
Costs:
High initial investment but very low cost per unit, especially for large production volumes.
Analysis:
Large-scale production is ideal for springs with a consistent design and high demand, such as in the automotive or household appliance industries.
While unit costs are low, flexibility and adaptability are low.
2. Batch production
Batch production is used for medium-sized quantities and offers some flexibility in producing variants or modifications.
The production processes are usually semi-automated.
Quantities:
Typical: 10,000 to 100,000 units.
Examples and applications:
Agricultural machinery: Springs in hydraulic systems or suspensions.
Industrial equipment: Springs for conveyor systems, presses or punching machines.
Advantages:
Flexibility: Series production allows adjustments to the production processes between batches.
Cost efficiency: Moderate costs due to the use of standardized processes, but with adaptation options for specific requirements.
Adaptability: Changes in design or specification can be realized within a production cycle.
Disadvantages:
Set-up times: When changing between series, machines have to be retooled, which causes time and costs.
Higher unit costs: Compared to mass production, unit costs are higher due to lower unit quantities.
Planning complexity: Mass production requires detailed planning to minimize set-up times and make production efficient.
Costs:
Moderate, with higher costs for machine changeovers and storage.
Analysis:
Mass production is suitable for applications where medium quantities and a certain flexibility in customization are required.
It offers a good balance between efficiency and flexibility, but at the expense of higher unit costs.
3. Small batch production
Small batch production is used for producing small quantities t, often for highly specialized products or prototypes.
This process is particularly in demand for springs that require specific properties or individual adjustments.
Quantities:
Typically: 100 to 10,000 pieces.
Examples and applications:
Aerospace industry: Springs for aircraft landing gear or rocket systems.
Medical technology: Specialized springs for surgical instruments or medical devices.
Advantages:
High level of customization: Small series offer maximum adaptability to specific customer requirements.
Fast adjustments: Changes can be implemented relatively quickly, which is ideal for prototypes and pilot projects.
Low initial investment: The costs for tools and machines are relatively low because less automation is required.
Disadvantages:
High unit costs: Due to the small number of pieces and the high level of manual work the cost per unit is higher.
Longer production times: Since less automation is used, production time is usually longer.
Costs:
High unit costs due to low quantities and manual manufacturing processes.
Analysis:
Small-batch production is particularly suitable for industries where specialized, customized solutions are required.
The advantage is the high flexibility and customization, but at the expense of efficiency and unit costs.
4. Variant production
Variant production enables the production of different product variants based on a basic model.
This allows a certain degree of standardization while at the same time allowing for a high degree of flexibility in adaptation.
Quantities:
Typically: 1,000 to 50,000 units, depending on the number of variants.
Examples and applications:
Automotive industry: suspension springs in different lengths and forces for different vehicle models.
Mechanical engineering: compression springs in different strengths and lengths for different machine types.
Advantages:
Flexibility in variant production: The production of several variants of a product is made possible by standardized basic production.
Cost savings through standardization: Common basic components reduce manufacturing costs.
Reduced inventory: Since only basic products have to be stored, storage costs are reduced.
Disadvantages:
Complex planning: Variant production requires precise planning and organization of production processes.
Set-up times: Although basic production is standardized, switching to different variants results in additional costs and time losses.
Limited economies of scale: Variability means that some of the advantages of mass production are lost.
Costs:
Moderate, depending on the number of variants produced.
Analysis:
Variant manufacturing offers an efficient way of producing different product variants based on standardized processes.
It is particularly suitable for markets with varying product requirements, such as the automotive or mechanical engineering industries.
5. Quota manufacturing
Quota manufacturing is a process based on predetermined production quantities, often for seasonal or fluctuating demand.
The production quantity is determined based on predictable or fixed quotas.
Quantities:
Varies greatly depending on requirements and production quota. Typically: 1,000 to 50,000 units.
Examples and applications:
Seasonal products: Manufacturing of springs for agricultural equipment that are in demand seasonally.
Contract production: Springs for projects with fixed production quantities (e.g. construction industry).
Advantages:
Demand-oriented production: Production takes place according to fixed quotas, which reduces storage costs.
Flexibility in the event of changes in demand: Adjustments to demand are possible, which enables flexible planning.
Planning security: Long-term planning is possible thanks to fixed production quotas.
Disadvantages:
Fluctuations in demand: If demand deviates from the quotas, overproduction or delivery bottlenecks can occur.
Higher costs for small quantities: With lower Production quantities can result in higher unit costs compared to other processes.
Costs:
Depending on production quantities and fluctuations in demand.
Analysis:
Quota production is suitable for industries with seasonal fluctuations or fixed production quantities.
It offers planning security, but carries risks in terms of demand forecasting and efficiency.
Complementary manufacturing processes: 6. Custom production
Quantities: 1 to 100 pieces.
Examples: Manufacturing of prototypes or custom-made products for highly specialized applications.
Advantages: Maximum customization, particularly suitable for prototypes and one-off projects.
Disadvantages: Very high costs per piece, long production times.
7. Batch production
Quantities: 100 to 1,000 units.
Examples: Production of small batches for specialized applications, such as in medical technology or aviation.
Advantages: Flexibility with small production quantities, suitable for special projects.
Disadvantages: Higher costs per unit, as economies of scale can only be used to a limited extent.
Each manufacturing process offers specific advantages and disadvantages that vary depending on the application, quantity and cost structure.
Large-scale and series production offer cost efficiency for large quantities, while small-scale and variant production offer high flexibility for specialized products. The choice of the appropriate process depends largely on the requirements of the end product, production capacity and economic goals.

The torsion spring:
Cylindrical torsion springs or also known as torsion springs, helical torsion springs are widely used and versatile machine elements components in the world of mechanics and spring technology.
The structure of a cylindrical torsion spring consists of a wire that is wound in a helical shape around a central axis in even turns.
torsion springs are used to absorb and release a rotating movement, a torque or a force and to guide the movement of the legs.
torsion springs are characterized by the ability to absorb and release deflections, forces or torques around a rotation axis and to guide the rotational movement.
torsion springs usually have a cylindrical spring body on which two legs are arranged.
The legs can be arranged tangentially, radially or axially, whereby each leg can have a different arrangement. Different spring end shapes can be attached to the end of the two legs, e.g. straight leg, hook shape, eyelet shape, round or square.
The terms "torsion spring", "torsion spring" and "torsion spring" refer to the same component.
