The Professional product accessories manufacturer

Q1: What is the minimum order quantity (MOQ) for injection molding?
A: MOQ depends on mold complexity, but typically ranges from 1,000 to 10,000 pieces. Prototype molds may allow smaller batches.

Q2: How long does it take to produce an injection mold?
A: Lead time varies from 3-8 weeks, depending on mold complexity, material availability, and design revisions.

Q3: Can you handle overmolding or insert molding?
A: Yes. Overmolding (combining multiple materials) and insert molding (embedding metal/plastic parts) are possible with proper mold design.

Q4: How do you prevent warping or sink marks in plastic parts?
A: Optimizing cooling channels, adjusting gate locations, and selecting materials with low shrinkage rates (e.g., ABS, polypropylene) help minimize defects.

Q1: What is the difference between CNC milling and turning?
A: CNC milling uses rotating tools to remove material from a stationary workpiece, while CNC turning rotates the workpiece against a fixed cutting tool.

Q2: Can you machine hardened metals like stainless steel or titanium?
A: Yes, but it requires specialized tooling (e.g., carbide or diamond-coated tools) and slower machining speeds to avoid tool wear.

Q3: What surface roughness (Ra) can you achieve?
A: Standard machining achieves Ra 3.2–6.3 μm. Precision grinding or polishing can reach Ra 0.4–1.6 μm.

Q4: Do you provide GD&T (Geometric Dimensioning and Tolerancing)?
A: Yes. We follow ASME Y14.5 standards to ensure parts meet specified geometric tolerances.

Q1: What material thickness can your stamping process handle?
A: Typically 0.5mm to 6mm for metals like steel, aluminum, and copper. Thicker materials may require progressive dies or multi-stage stamping.

Q2: How do you ensure consistency in high-volume stamping?
A: Automated presses, precision tooling, and regular quality checks (e.g., CMM measurements) ensure consistent output.

Q3: Can stamped parts include bends or embossed features?
A: Yes. Features like bends, holes, and embossing can be integrated into the die design.

Q4: What is the cost difference between single-stage and progressive dies?
A: Progressive dies are more expensive initially but reduce labor costs for high-volume production. Single-stage dies suit low-volume runs.

Q1: What materials are molds typically made from?
A: Common materials include tool steel (e.g., P20, H13), aluminum (for prototypes), and hardened steel (for high-volume production).

Q2: How many cycles can a mold withstand?
A: Aluminum molds: 10,000–50,000 cycles. Steel molds: 500,000+ cycles, depending on material and maintenance.

Q3: Can you modify an existing mold for design changes?
A: Yes, but modifications (e.g., adding/removing features) may require welding, re-machining, or EDM (electrical discharge machining).

Q4: Do you provide mold flow analysis?
A: Yes. We simulate filling, cooling, and warping to optimize mold design and prevent defects.
