In the field of medical device manufacturing, the quotation for injection molds of medical connectors is a complex issue influenced by numerous factors. This article will delve into these factors to help readers fully understand the quotation mechanism for injection molds of medical connectors and provide references for industry professionals to formulate reasonable quotation strategies.

I. Mold Design Complexity: A Key Factor Influencing Quotation

• Product Structure
  The internal channels of medical connectors are complex. For example, minimally invasive surgical connectors have difficult - to - design cores. Special structures are required for demolding, and uneven cooling complicates the process, significantly increasing costs. High - precision threads and snap - fit structures have small tolerances, and the molding and demolding mechanisms are complex, which significantly add to the manufacturing costs.
• Parting Line Design
  The parting line affects mold processing and product quality. For complex connectors, the parting line design is fine. The presence of undercuts increases the difficulty of part assembly, simulation time, and costs.
• Demolding Mechanism
  Complex - shaped medical connectors require special demolding mechanisms. To ensure precision and quality, the demolding action must be smooth, which requires special device materials and test optimization, increasing the design difficulty and cost.

II. Mold Material: Balancing Performance and Price

• Correlation between Performance and Price
  Injection molds for medical connectors need to be resistant to pressure, wear, corrosion, and thermally stable. High - performance materials such as H13 and S136 steel can meet these performance requirements but are expensive, increasing the manufacturing cost.
• Impact of Brand Quality
  Well - known brand materials have high quality but are expensive, such as Assab from Sweden. Ordinary brand materials have lower prices but may have slightly inferior mold life and precision. When choosing, it is necessary to comprehensively consider production needs, cost budgets, and mold life and precision requirements.

III. Mold Size and Specifications: Important Factors in Cost Variation

• Impact of Product Size
  Large medical connectors, such as large infusion tube connectors, require more mold materials, consume more energy and labor hours, and have higher requirements for equipment specifications and precision, leading to increased costs.
• Relationship with the Number of Cavities
  Increasing the number of cavities can improve production efficiency, but it also makes the mold structure more complex. Changing from a single - cavity to a multi - cavity mold requires a complex gating system, and the layout of runners and ejection mechanisms in multi - cavity molds is more complex, increasing the design and manufacturing difficulty and cost.

IV. Machining Precision and Surface Quality: Quality Improvement and Cost Increase

• Improvement in Dimensional Precision
  To achieve high precision, advanced equipment and processes such as high - speed milling and slow - wire electrical discharge machining are required. These equipment are expensive and difficult to maintain, and labor costs are high, increasing the machining cost.
• Surface Roughness Requirements
  The surface roughness of the mold cavity and core needs to reach Ra0.8 - Ra0.2μm, which requires multiple fine polishing processes. High - quality materials and equipment are used, and the manual labor intensity is high with low efficiency, leading to increased costs. However, good surface quality is important for product performance.

V. Production Batch and Service Life: Consideration of Long - term Costs

• Impact of Expected Output
  In large - scale production, the mold needs high - quality materials and a strengthened structure. Long - term production requires precision machining and maintenance, which increases costs.
• Relationship with Mold Life
  Long - life molds have high initial costs but require fewer replacements, which can reduce downtime and labor costs. Short - life molds have low initial costs but need frequent replacements, and the overall cost may be higher. When choosing a mold, it is necessary to comprehensively consider production needs and cost budgets.

VI. Manufacturing Process and Technical Level: Key Factors in Cost Control

• Impact of Processing Technology
  Advanced processes such as high - speed cutting and electrical discharge machining require high - end equipment. The equipment procurement and maintenance costs are high, and the consumable costs are large, directly increasing the manufacturing cost. However, they can improve mold precision and efficiency, shorten the manufacturing cycle, and reduce long - term costs.
• Value of the Manufacturer's Technical Strength
  Manufacturers with high technical levels can accurately control each link of mold manufacturing, reduce the scrap rate and maintenance costs, and improve product quality. Although their quotations are high, they can help customers reduce costs in the long run. Their high charges reflect their professional value and cost - control ability.

VII. Other Factors: Cost Factors That Cannot Be Ignored

• Cost of Trial Molding and Debugging
  Trial molding consumes raw materials, energy, and labor. Multiple trial moldings can multiply the cost.
• Cost of Transportation and Packaging
  Transportation distance, mode, and special packaging requirements affect the transportation and packaging costs of the mold. Long - distance transportation or special packaging can significantly increase the cost.
• Market Supply - Demand Relationship
  When the market demand is high, the mold price rises. When the order volume is low, the price may be reduced.

In conclusion, the quotation for injection molds of medical connectors is influenced by a combination of multiple factors. In actual operations, it is necessary to comprehensively consider all factors, weigh the pros and cons, and formulate reasonable quotation strategies to ensure mold quality while maximizing economic benefits, meeting the needs of injection mold manufacturers for medical connectors and the market, and improving industry competitiveness.
