Prototyping, Tooling & Quotation

From an early sample to a production mould, start with a clear brief. Understand what to send, what shapes the cost and how JingZhan reviews the next step with you.

A useful quotation starts with the right information

You do not need to solve every manufacturing question before contacting us. Send what you have and clearly mark any open decisions. The aim is to establish a shared technical and commercial basis before work begins.

Project information checklist
What to provideWhat it helps us review
2D drawing and 3D modelPart number, revision, units, geometry and critical dimensions. Send STEP or another agreed model format, plus a dimensioned PDF drawing where available.
Material and finishSpecified resin family and grade, colour, texture, polished areas, inserts and any required supporting documents.
Function and assemblyIntended use, service conditions, mating components and any fit, sealing or appearance restrictions.
Quantity and demandSample quantity, first production order, expected annual demand and likely repeat-order pattern.
Quality and deliveryCritical checks, sample-approval requirements, report scope, packaging, destination and requested milestones.

Only have a sample or a concept? Start with photographs, overall dimensions and a description of the job the part must do. Additional design definition may be needed before a firm quotation. Discuss confidentiality arrangements before sending sensitive project files.

Give each sample a clear purpose

Sampling is most useful when we agree what it needs to prove. You may need to explore shape and assembly, evaluate a material, or check parts produced from the intended mould. These are different stages, and the appropriate route is selected during project review.

  • For an early prototype, define the fit, access or appearance questions to be answered.
  • For a mould trial, agree the resin, sample quantity, critical dimensions and visual checks.
  • For production release, identify the required inspection evidence and any customer-led application tests.

Record any difference between a prototype and the intended production component, including material, manufacturing method and surface finish. A prototype should not be treated as proof of every production or service requirement.

Prototype method, sourcing route, trial rounds and test responsibilities are confirmed in the quotation. No particular prototype process is assumed to be included.

Understand what shapes the price

A mould price and a moulded-part price answer different questions. Comparing offers is easier when each cost is connected to a defined scope, quantity and acceptance requirement.

01

Prototype and sample work

Design maturity, sample method, material, quantity, finishing, fixtures and the agreed evaluation or reporting work affect this stage. Separate early prototype work from samples produced during mould trials.

02

Tooling development

Part size and geometry, cavities, tool material, slides or other mechanisms, runner design, surface finish, machining and inspection scope influence the tool proposal. The intended demand and expected use of the mould also belong in the discussion.

03

Production parts

Specified resin, part and runner material usage, cycle and handling requirements, batch size, inserts or assembly, inspection, finishing and protective packaging influence the piece-price basis.

Compare the same scope, not only the total.

Check which trials and sample quantities are included, how requested changes are handled, which reports and packaging are covered, and whether transport, taxes or other commercial items are included or excluded. Payment milestones, mould ownership, storage and release arrangements should be confirmed in writing.

Agree the tooling basis before manufacture

The design-for-manufacture review connects your component requirements to the proposed mould. It is the stage to discuss release direction, parting lines, gates, ejection, difficult features and any restricted cosmetic or functional areas.

  • Confirm the drawing and model revision being quoted.
  • Identify critical dimensions and the proposed inspection approach.
  • Review tool configuration and any design assumptions requiring approval.
  • Clarify the sample, report and acceptance scope before release.

DFM comments are engineering proposals for review. Changes to your component design, material or acceptance requirements need approval; they are not made silently to match the quotation.

How to start working with JingZhan

  1. Send the project briefProvide the drawing or sample information, quantity, material and desired milestones.
  2. Resolve the open questionsReview application, DFM, tooling route and any missing acceptance requirements.
  3. Confirm the quotationAgree scope, exclusions, price basis, responsibilities and commercial milestones.
  4. Release the agreed workApprove the applicable files and tooling or sampling plan before manufacture.
  5. Review the samplesEvaluate the agreed dimensional, appearance and assembly evidence. Record corrections or approval.
  6. Plan production and repeat supplyConfirm the order quantity, material readiness, packaging and delivery after the required approvals.

Lead time is planned around design approval, material and tooling readiness, trial feedback and capacity. MOQ and batch economics are reviewed for the actual part; this page does not promise a fixed price, delivery time or minimum quantity.

Questions before requesting a quotation

What if I only have a sample or an early concept?

Send clear photographs, approximate dimensions, the intended function and any known material or assembly requirements. JingZhan will review what additional design information is needed before a firm manufacturing scope can be confirmed.

Are prototype, mould and production-part charges the same item?

No. They are different scopes and should be identified separately. The quotation should make clear which sample work, tooling, trial, inspection and production quantities are included.

Can you give a fixed price from a photograph?

A photograph helps start the discussion but normally does not define internal geometry, tolerances, material or acceptance requirements. Any early estimate remains subject to the stated assumptions and further technical review.

How long will sampling and tooling take?

Timing depends on the design status, material availability, tool structure, finish, inspection scope and approval rounds. JingZhan reviews the required milestones and confirms a project-specific schedule rather than a universal lead time.

Is there a standard minimum order quantity?

Sample and production quantities are reviewed separately. Tool setup, resin purchasing, the part design and packaging needs influence a practical batch. Ask for the quantities relevant to your programme rather than assuming one MOQ fits every component.

Tell us what you want to make

Start with your part, intended use, sample quantity and expected production demand. Tell us which material or design decisions are still open. For project files, email ljf@jz-mould.com and include the part number and revision.
