Low-Volume Manufacturing

The Sweet Spot Between Prototype and Mass Production.

50 pieces. 500 pieces. 5,000 pieces. The quantities that are too many for a prototype shop and too few to justify hard tooling. Huasheng is built for exactly this range.

  • ▸Bridge production while your steel mold is cut (saves 8–12 weeks)
  • ▸Niche volumes that will never need mass tooling — industrial, medical, aerospace
  • ▸50–5,000 pieces on CNC, sheet metal, or vacuum casting
  • ▸Dedicated project manager assigned for orders over 100 pieces

Design

Design guidelines

Follow these rules for optimal cost and lead time. Our engineers flag any DFM issues during quote review.

01
Design for Manufacturing, Not Just Assembly

At 500+ pieces, small design changes compound. Our engineers review every project for DFM — loose tolerances where possible, consolidated operations, and finish standardization.

02
Consider Modular Tooling

For repeating geometries, we invest in modular jigs and fixtures. Amortized across your first 200 pieces, then free for future orders. This typically saves 30% on re-order unit cost.

03
Standardize Finishes

Limit finish options. A part with 5 surface finishes takes 5 queue slots in our paint shop. One finish, or 2 max, cuts lead time by 30%.

04
Inspection Plan Before First Article

Define critical dimensions, sample size, and AQL level upfront. Our QC team builds a dedicated inspection plan for production orders.

05
Plan Shipping Early

Sea freight is 4–6x cheaper than air for 100 kg+ shipments. Add 25 days to lead time if you're not in a rush. We consolidate shipments from multiple jobs when possible.

06
Talk Payment Terms

For orders over $10k, we offer 30/70 or 50/50 payment terms. For repeat customers, net-30 is available after the first order.

How it works

From drawing to part

  1. 01
    Pilot run of 5–10 pieces to validate design and process
  2. 02
    First Article Inspection (FAI) with full dimensional report
  3. 03
    Production release after FAI sign-off — all parts from same setup
  4. 04
    In-process inspection per AQL plan (typically every 50 pieces)
  5. 05
    Final inspection, packaging, shipping documents, DDP or FOB

FAQ

Frequently asked questions

Q01What's the MOQ?+
No minimum. But unit economics shift dramatically around 100 pieces — below 100, CNC machine setup time dominates. Above 250, we can often drop unit price by 20–30% vs prototype pricing through optimized setups and modular fixtures.
Q02How do you handle batch-to-batch consistency?+
First Article Inspection on every production batch, matched to the golden sample from the pilot run. For orders over 500 pieces, we preserve CNC programs, fixtures, and inspection plans — a re-order runs to the same spec without re-qualification.
Q03Can you handle bridge production before my injection mold is ready?+
Yes — this is one of our most common use cases. Vacuum casting handles 10–100 pieces bridge, CNC handles 100–1,000 pieces bridge. We'll match material properties as closely as possible to your production resin so testing transfers.
Q04Do you offer contract manufacturing agreements?+
Yes. For recurring annual volume, we offer fixed pricing agreements with inventory buffers (typically 2–4 weeks of safety stock). Minimum annual commitment is $50k.
Q05Are you IATF 16949 / ISO 13485 certified?+
We operate to IATF 16949 process controls and are pursuing certification. Not currently ISO 13485 certified — for medical device production, we recommend validating your final supplier, but for pilot runs and regulatory submission samples, we work with dozens of medical customers.
