There are a large number of hidden charges in the prototype processing industry, and many customers initially see low-priced quotes, but the final settlement cost is 30% -50% higher. Here are the 5 most common hidden cost traps and avoidance strategies.
Trap 1: DFM design deficiency leads to rework in the later stage.
Some prototype factories quote directly based on the drawings, skipping manufacturability analysis, and only discover design defects during processing, requiring redesign and reprocessing, doubling the cost. METALTAR PROTOTYPE requires a DFM review before processing, providing a manufacturability analysis report, and outputting drawings in STEP/IGS format to clarify benchmarks, tolerances, and assembly requirements.
Trap 2: Mismatch of materials leads to substandard performance.
To reduce costs, manufacturers may recommend low-priced alternative materials, but mismatched performance may cause prototype failure and require re sampling. METALTAR PROTOTYPE selects materials based on their functions, prioritizing materials that are consistent with mass production to ensure that test data can be referenced. AL7075 aluminum alloy is recommended for structural load-bearing components, ABS or PC for exterior parts, and stainless steel for high-precision moving parts.
Trap 3: One size fits all process leads to a loss of both precision and cost.
In order to simplify the quotation, the manufacturer adopts a single process for all parts, resulting in insufficient accuracy or cost waste. METALTAR PROTOTYPE adopts a mixed process strategy, with high-precision structural parts using five axis CNC, complex curved shells using SLA photopolymerization 3D printing, and small batch appearance parts using silicone replication.
Trap 4: Lack of precision detection leads to assembly scrap.
Most prototype factories only use calipers for sampling, skipping the three coordinate inspection, resulting in single piece qualification and assembly scrap. METALSTAR PROTOTYPE is a comprehensive inspection system established, with key dimensions inspected using three coordinate measurement and requiring the issuance of CMM reports. Moving parts undergo no-load/load testing.
Trap 5: The low price trap leads to hidden price increases in outsourcing and subcontracting.
Some small factories offer extremely low prices, but all core processes are outsourced, resulting in hidden price differences due to multi-level subcontracting. METALTAR PROTOTYPE is a fully automated physical factory with transparent pricing, requiring material, process, quantity, and delivery time to be listed item by item.
Choosing METALTAR PROTOTYPE will save you time, effort, and cost in your prototype processing.
