FAQ

Common questions from buyers

Plastic mold costs at Topworks typically range from $1,500 to $80,000, depending on part size, complexity, cavity count, and steel grade. A simple single-cavity mould for a small part starts at $1,500. A medium-complexity multi-cavity automotive mould averages $15,000–$30,000. Large bumper or appliance moulds with hot runners can reach $50,000–$80,000. Send your part drawing for an exact quote in 24 hours.

Standard lead time is 35–55 days from DFM approval, depending on mould size and complexity. Simple prototype moulds: 25–35 days. Production moulds: 40–55 days. Hot-runner multi-cavity moulds: 55–75 days. Topworks offers express options for urgent projects (50% faster, surcharge applies).

For moulds: 1 piece. We build single-cavity prototype moulds for as low as 100-piece runs. For injection-molded parts only (using your existing mould), MOQ is typically 500–1,000 pieces. We can accommodate low-volume production runs of 100–10,000 pieces using soft tooling.

Yes. We sign NDAs before reviewing any 3D files. Topworks has never had an IP dispute in 20+ years. Your designs are stored on encrypted servers, accessible only to assigned engineers, and we do not subcontract your project to outside parties without written approval.

Topworks moulds are rated for 500,000 to 1,000,000+ cycles depending on material and design. Hardened steel (H13, S136) moulds running standard thermoplastics typically exceed 1M cycles. We provide a lifetime warranty against manufacturing defects: if the mould fails before its rated cycle count due to our workmanship, we repair or replace it at no cost.

Yes. We ship to 50+ countries with experience handling US, EU, UK, Canada, Australia, Japan, and Brazil customs. We offer FOB, CIF, and DDP terms. DDP shipping includes door-to-door delivery with all duties prepaid — you receive the mould or parts ready to use.

Standard terms: 50% deposit, 50% before shipment (after T1 sample approval). We accept T/T (wire transfer), L/C for orders over $50K, and credit card via PayPal for orders under $5K. For repeat clients with payment history, we offer net-30 terms.

Yes — free DFM analysis on every project. Our engineers will review your 3D file and flag mouldability issues (draft angles, wall thickness variation, undercuts, weld lines, sink marks). We typically identify 5–15% cost-reduction opportunities before tooling begins. We also offer paid design-for-manufacturing consulting if you need redesign help.
