Custom parts for the Packaging sector

Industry Solutions

Packaging Manufacturing — Custom Parts from China

A packaging line only runs as well as its tooling. We machine molds, machine parts and jigs, print prototypes and assembly aids, mold caps, closures and containers, and fabricate guards and brackets — for food, beverage, cosmetic, pharma and retail packaging. From one prototype to full production.

Industry Application

Packaging Parts We Build Every Day

We work with packaging machine builders, mold makers, converters and brand owners. These are the parts our shops produce most often for the packaging sector:

Packaging Machine Parts

Cams, sealing jaws, filler nozzles, star wheels and guide rails machined for smooth, repeatable motion.

Molds & Mold Components

Cavity and core inserts, sliders, ejector pins and hot runner parts built to give clean parts shot after shot.

Jigs, Fixtures & Assembly Aids

Line-side jigs, gauges and end-of-line tooling that keep assembly and packing fast and consistent.

Caps, Closures & Dispensers

Threaded caps, flip tops, pumps and sprayers molded for a smooth open every time.

Food & Beverage Components

Containers, trays, cups and multipack carriers molded in food-grade PP, PET and PS.

Cosmetic & Pharma Packaging

Jars, bottles, tubes and device packaging with the finish quality shelf presence demands.

Labeling & Coding Fixtures

Label applicator parts, print fixtures and sensor mounts positioned exactly where the line needs them.

Conveyor & Handling Parts

Side rails, chutes, wear plates and brackets that move bottles, cartons and cases without jams.

How we help

Why Packaging Teams Choose YiguProto

A downed line costs money every minute. We manufacture tooling and parts to your design, check every critical dimension, and ship parts that fit and run the first time.

Tooling That Fits

We review your drawings before cutting steel. Parts that fit the first time keep your line running.

Mold-Level Precision

Micron-level fits on mold components and machine parts — the difference between clean parts and jams.

Speed to the Line

Printed prototypes in days, machined parts in days, and quotes within 24 hours to keep launches on schedule.

One Partner, Four Processes

Machining, printing, molding and sheet metal in one place. Fewer vendors, fewer delays.

Solution 01 · CNC Machining

CNC Machining for Packaging

Most packaging tooling is machined metal. We cut mold components, cams, sealing jaws, filler nozzles and guide rails from tool steel and aluminum, hardened and ground to fit — so your line runs clean parts at full speed.

Mold Components & Inserts

Cavity and core inserts, sliders, ejector pins and lifters machined to micron-level fits.

Machine Parts & Cams

Sealing jaws, filler nozzles, star wheels, cams and guide rails that survive millions of cycles.

Jigs, Gauges & Fixtures

Assembly jigs, check fixtures and line-side gauges that keep quality repeatable.

Solution 02 · 3D Printing

3D Printing for Packaging

Packaging designs change fast, and printed prototypes put the pack in your hands in days. Test fit on the line, check shelf presence, iterate the mold design — no tooling, no minimum order.

Packaging Prototypes

Bottles, cartons, clamshells and trays printed for fit, shelf and drop tests before you commit to a mold.

Mold Design & Soft Tooling

Printed mold inserts and casting patterns for pilot runs — prove the design, then cut steel.

Line Jigs & Assembly Aids

Lightweight printed jigs, guides and end-of-line tools, made fast when the line needs them.

Best forPrototypes, fit and shelf tests, printed tooling, jigs and complex shapes
ProcessesSLA, SLS, MJF and FDM printing
MaterialsPLA and PETG for quick checks; nylon and glass-filled nylon for functional parts; PC; tough resins for snap-fit tests; TPU for seals and pads
DetailsParts print straight from your CAD file — no tooling needed
Quantities1 piece to small batches — no minimum order
TurnaroundPrototypes often ship in 1 to 3 days

Solution 03 · Injection Molding

Injection Molding for Packaging

When your pack design is proven, molding gives the lowest cost per piece. We mold caps, closures, containers, trays and cups in food-grade and engineering plastics — with the finish and repeatability production volumes demand.

Caps, Closures & Dispensers

Threaded caps, flip tops, pumps and sprayers molded for a smooth open every time.

Containers, Trays & Cups

Food-grade PP, PET and PS containers, trays and multipack carriers in volume.

Cosmetic & Pharma Packs

Jars, bottles, tubes and device packaging with the finish quality shelf presence demands.

Best forCaps, closures, containers, trays, cups and small plastic parts in volume
ProcessesRapid tooling, production molds, family molds, insert molding
MaterialsPP, PET, PS, PLA, ABS, PC, POM, PEEK — plus masterbatch color matching
ToolingAluminum bridge tooling for pilots; hardened steel molds for production
QuantitiesFrom pilot runs to millions of pieces
TurnaroundPrototype parts in days; production timing follows the tooling build

Solution 04 · Sheet Metal

Sheet Metal Fabrication for Packaging

Sheet metal builds the structure around the pack. We laser-cut, bend and weld aluminum and steel into machine guards, brackets, side rails and chutes — with no tooling for prototypes and fast turnaround from one unit to volume.

Machine Guards & Panels

Safety guards, covers and access panels formed to your drawing for line compliance.

Brackets & Mounts

Sensor brackets, conveyor mounts, roller brackets and equipment stands built to fit.

Conveyor & Handling Parts

Side rails, chutes, wear plates and guides that move cases and cartons without jams.

Best forGuards, covers, brackets, conveyor parts, chutes and formed panels
ProcessesLaser cutting, CNC bending, punching, welding and assembly
MaterialsAluminum 5052 / 6061, stainless steel 304 / 316, steel

How we work

From File to Filling Line — Five Clear Steps

You always know where your project stands. Here is the path most packaging projects follow with us:

Share your files

Send 2D drawings or 3D models (STEP, STP, IGES, STL). Tell us the product, the quantity and the conditions on the line.

Free DFM review & quote

Our engineers review the design and return a quote within 24 hours, with feedback on material, tooling and cost.

First article

We make a first sample and run dimensional checks. You approve fit and finish before the rest are made.

Pilot run

We confirm the process with a small batch. Mold tuning and design changes happen here — while change is still cheap.

Production & delivery

We scale up with stable quality and on-time delivery. Inspection reports travel with every batch.

Quality & Trust

Quality You Can Verify

Good parts are proven, not promised. Our quality system checks every stage, so your tooling fits and your parts run clean.

Incoming Material Control

Material certificates for every lot of tool steel, aluminum and food-grade resin.

First Article Inspection

Full dimensional checks on the first piece before the batch runs.

In-Process Checks

Operators verify critical features during the run — not only at the end.

Final Reports & Traceability

Dimensional and inspection reports with every order. Lot traceability on request. Your files stay confidential.

Materials & Finishes

Built from the Right Stuff

Material and finish decide how tooling wears and how a pack looks on shelf. Tell us the application, and we will suggest a grade that fits your design and budget.

Tool Steels & Metals

H13, P20 and 17-4PH for molds; aluminum 6061 and 7075 for machine parts and fixtures.

View metal materials →

Packaging-Grade Plastics

PP, PET, PS, PLA and engineering plastics for food-contact parts, caps and containers.

View molding materials →

Protective Finishes
