Cost and Quotation

We believe in transparency and clear communication with our clients. Our cost structure is carefully designed to balance quality and affordability, while our delivery lead times are optimized to ensure we meet your business requirements. Below, we provide a detailed breakdown of how we manage costs and delivery for our injection molding products.

Raw Material Costs

Raw materials are a major part of the manufacturing cost for injection-molded products. We source a wide range of high-quality materials, including various types of plastic resins like ABS, PC, PP, PE, and PVC, as well as additives and pigments. The choice of material depends on your product’s functional needs and appearance, such as strength, flexibility, heat resistance, or look.

  • Material Sourcing: We work with trusted suppliers to ensure consistent quality and competitive pricing.
  • Material Type & Grade: Different material grades affect the performance and cost of your product. High-performance engineering plastics may cost more than standard materials.
  • Material Waste: We strive to minimize waste during production to reduce costs and environmental impact. This helps us pass savings on to you.

Mold Costs

Manufacturing custom injection molds is essential for injection molding. Mold costs are one-time fees that vary based on the product’s complexity and the number of cavities in the mold.

  • Mold Design & Prototyping: The design and prototyping stage is crucial in ensuring that your mold will produce the desired part quality and quantity. We work with you to refine the design and reduce costly changes later in production.
  • Mold Material: The material used for making the mold (such as steel, aluminum, or alloy) directly impacts the mold cost. Steel molds are more durable and suited for high-volume production, while aluminum molds are typically less expensive but suitable for lower-volume runs.
  • Mold Life & Maintenance: Molds can run last for hundreds of thousands of cycles, but regular maintenance may be required to maintain their performance, especially for high-precision molds. We ensure that molds are built to last and are properly maintained to avoid unplanned downtime during production.

Production and Processing Costs

Production costs are determined by the complexity of the injection molding process, the efficiency of the equipment, and the required post-processing steps (such as assembly or finishing).

  • Cycle Time: The cycle time for each injection cycle depends on the material, part size, and complexity of the design. More intricate parts may take longer to molding, which affects the overall cost of production.
  • Tooling & Setup: Setting up machines, adjusting molds, and running test batches all take time and are factored into the production cost. For high-volume orders, we can optimize production schedules to minimize setup time and reduce costs.
  • Post-Processing: Many injection molded products require secondary processes such as trimming, polishing, painting, or assembling. These additional steps are factored into the overall cost.

Labor Costs

Skilled labor is essential in injection molding. This includes machine operators, mold setup technicians, quality inspectors, and assembly staff. Labor costs can vary depending on production volume and the skill levels required.

  • Skilled Workforce: Our team is highly trained in operating advanced injection molding machines and ensuring quality control throughout the process.
  • Quality Assurance: Labor costs are also affected by the number of quality checks required to meet strict customer specifications.

Shipping and Logistics Costs

Shipping costs depend on the order’s destination, volume, weight, and the chosen shipping method. We offer a variety of shipping options to help you manage costs and ensure timely delivery.

  • International Freight: We coordinate sea freight, air freight, and express courier services depending on the urgency of your order. Sea freight is typically more cost-effective for larger shipments, while air freight is faster but more expensive.
  • Customs Duties & Taxes: Import duties, taxes, and customs clearance fees vary by country and region. We can provide assistance in calculating these costs to ensure there are no surprises.
  • Packaging: We ensure that all products are securely packaged to prevent damage during transit. The cost of packaging is included in the shipping costs.
