Custom optical mouldings from tooling to repeat supply

JingZhan supports custom optical injection-moulding projects covering lens components, transparent covers, optical supports and related housings. The work begins with approved customer data and connects tooling, trial samples, inspection and repeat part supply. Pictured components are examples of different geometries, not a single standard specification.

DESIGN AND MANUFACTURING

Key processing requirements

Separate optical and mechanical requirements. Define the light-transmitting area, optical profile and mounting datums. Identify which features control fit, appearance and optical performance.
Choose an application-specific resin. Review PC, PMMA or other suitable optical materials against transmission, temperature, impact, colour and environmental exposure. Confirm the exact grade before trials.
Plan the tool around surface quality. Review flow, cooling, gates, ejectors and parting lines before tool manufacture. Agree polish or texture and measurable acceptance rules for visible areas.
Approve samples before series release. Check dimensions, appearance and assembly using agreed methods. Optical output needs its own test with the specified light source or finished module.

TECHNICAL SPECIFICATIONS

Parameters agreed for your part

Custom-manufacturing options, not common measured values for every pictured part.
Parameter	Project specification
Manufacturing process	Custom plastic injection moulding with dedicated tooling and sample approval.
Product scope	Lens components, clear covers, optical supports and related moulded housings.
Resin options	Optical-grade PC and PMMA; COC/COP or other resins assessed for a particular design.
Part dimensions	To customer 2D/3D drawings and DFM review, not a universal stock size.
Tolerance	Critical-feature requirements agreed against datums, function and measurement method.
Appearance and optical criteria	Approved surface sample plus project-specific colour, transmission or light-output criteria where required.
Tooling options	Single- or multi-cavity moulds; insert steel, runner and finishing route confirmed in the proposal.
Production records	Inspection, material documents and lot-identification scope agreed at quotation.

PRODUCTION AND REPEAT SUPPLY

Equipment, lead time and order planning

The manufacturing route can combine Makino and other listed CNC centres, Sodick/Makino EDM, mirror-polishing equipment and injection moulding. Listed presses include Nissei 50–100 T, Chen Hsong 128–260 T and Haitian 500 T options. Engineering selects the actual machine and inspection method for each tool; optical-test resources are agreed separately.

Indicative quotation planning only. Final MOQ and lead time are confirmed for the project.
Planning item	Basis for quotation
DFM review	Indicative 3–5 working days after complete drawings and requirements.
New tooling	Indicative 4–8 weeks to first mould trial after tool-design approval and commercial release; corrections and customer validation are additional.
Order quantities	Initial planning basis: 500-piece pilot or 1,000-piece repeat batch per part number, resin and colour, subject to quotation.
Repeat orders	Indicative 10–15 working days after materials and the production slot are confirmed, excluding transit.

Keep repeat orders on an approved baseline

For ongoing OEM supply, agree the drawing revision, resin, accepted samples, inspection plan and packing before release. Annual demand informs tooling and procurement; shipment size and requested dates determine each batch. Tool maintenance, spare inserts and changes affecting the approved part should be reviewed as part of the supply arrangement.

Tooling investment is quoted separately from the piece price. Share annual demand and the quantity per release so cavity count, material procurement and batch cost can be reviewed together.

RELATED APPLICATIONS

Where these components can be used

LED illumination and warning-light lens assemblies.
Instrument viewing covers and transparent equipment components.
Optical locating structures, coloured housings and other drawing-defined clear mouldings.

Suitability depends on the complete assembly and its validation. Material data and a dimensional report do not by themselves establish beam distribution, protective performance or device approval.

Dark-coloured domed moulded component sample — Dark-coloured dome sample; material, tint and light transmission require project-specific confirmation.
