We provide full‑range project‑management services for enterprises, from product concepts and drawing evaluation to finished‑goods delivery.
About Us
Professional Plastic Supply‑Chain Project Manager
Qilinji Business specializes in plastic‑product development and mass‑production supporting services. After years of resource accumulation, we have built a complete, strict evaluation, admission and tracking system for our manufacturing partners.
More than a simple factory broker, we act as your dedicated supply‑chain coordinator: assessing manufacturability, planning mold solutions, selecting matched production resources, monitoring samples and mass‑production quality, coordinating complex post‑mold processes, and managing inspection, consolidation and shipment.
We help you avoid multi‑party communication costs, lower risks of design failure, delivery delays and quality‑control failures.
Our Core Values
✅Result‑oriented, objectively match the most suitable manufacturing resources
✅Full‑process transparent tracking, regular updates on sampling, production and shipment
✅Respect client intellectual property, enforce strict non‑disclosure rules
✅Offer practical multi‑option plans balancing quality, cost and lead‑time
✅Long‑term partnership mindset, not only one‑off order service
Our Services
✅ DFM Design‑for‑Manufacturability Review
Process evaluation based on 3D files or physical samples. Identify risks like sink marks, sticking, draft angles, wall‑thickness and assembly issues in advance. Provide practical suggestions to reduce costly mold revisions.
✅ Mold Solution Planning & Sourcing
Suggest hot‑runner / cold‑runner designs, cavity quantities and steel grades according to product complexity and estimated order volume. Compare mold shops on price, expected service life and lead‑time.
✅ Injection‑Molding Project Management
coordinate trial shots, color‑sample confirmation, parameter freeze‑in and mass‑production scheduling. Monitor dimensions, surface finish, toughness and color consistency. Resolve production deviations quickly.
✅ Full‑Range Surface‑Finish Management
Silk‑screen printing, laser engraving, spray‑painting, UV clear coat, texture‑etching, vacuum‑metallization, hard‑rubber over‑molding and other post‑processing solutions.
✅ Assembly & Custom Packaging Solutions
Simple component assembly, ultrasonic welding; custom color boxes, white boxes, hang‑tags, manuals, adhesive labels, moisture‑proof bags and complete packing‑plan coordination.
✅ Final Inspection, Cargo Consolidation & Logistics
Pre‑shipment inspection following AQL or custom‑agreed standards. Consolidate goods from multiple factories. Arrange domestic trucking, sea freight, air freight, courier service and document preparation.
Why Work With Qilinji
Vetted‑Supplier Qualification System
Manufacturing partners are audited on production capacity, equipment, QC procedures and historical delivery‑performance records before being added to our resource pool.
Neutral Third‑Party Project Oversight
We represent your interests during production. We actively discover, report and coordinate solutions for hidden manufacturing issues, instead of only relaying factory statements.
Formal Non‑Disclosure Protection
Official NDA agreements are available for new‑product projects. Drawings, samples and business plans are strictly controlled with limited distribution.
Multi‑Option Comparative Support
For complex items, we prepare 2‑3 alternative supply‑chain plans, listing pros‑and‑cons, cost ranges and lead‑times for your easy decision‑making.
Cross‑Process Resource Integration
Mold, injection‑molding, plating, printing, packaging and shipping resources are connected. Even multi‑step complicated products can be managed under one single project.
Hands‑On Project Execution Experience
Past‑project experience covers consumer‑electronics parts, household goods, hand‑tool components, promotional gifts and many other plastic‑based articles.
Standard Cooperation Workflow
In‑Depth Project Requirement Discussion
Share your 3D files, 2D drawings, physical samples or reference photos. Confirm required material, colors, estimated quantity, special finishes, lead‑time targets and QC acceptance criteria.
Manufacturability Review & Formal Quotation
We analyze production challenges, select matched supply‑chain partners and send you a full proposal including mold cost, unit price, sample turnaround, mass‑production schedule and payment suggestions.
Prototype / Mold Fabrication & Sample Confirmation
After plan approval, prototypes or production molds are made. Finished samples are sent for your verification on appearance, dimensions, assembly and functional performance.
Mass‑Production Full‑Cycle Supervision
Signed‑off samples serve as the quality benchmark. Production schedules are tracked. Color, surface and dimension checks are followed up. Any abnormality is reported instantly with corrective‑action options.
Final QC, Custom Packing & Cargo Shipment
Pre‑shipment inspection is performed per agreed standards. Goods are packed to your requirements. Cargo is consolidated, shipping is arranged, and packing lists & tracking numbers are shared with you.
