A plastic part reaches stable production through a connected material, mould, machine and operating process. CHINAPLAS 2027 allows automotive, packaging, medical, electrical and consumer-product buyers to examine much of that chain in one venue. The visit becomes more useful when every conversation starts from a defined part or package rather than a general request for a new resin or machine.
CHINAPLAS runs from 13–16 April 2027 at Shenzhen World Exhibition & Convention Center (Bao’an). Its official theme zones cover raw materials and additives, injection moulding, extrusion, blow moulding, film, moulds, auxiliary and testing equipment, automation and recycling. The breadth supports several different buyer missions.
| Buyer mission | Starting evidence | Useful result from the show |
|---|---|---|
| Develop a new plastic part | Drawing, function, service conditions and forecast volume | A feasible material-process-tool route |
| Transfer or localise production | Approved sample, current specification and defect history | A controlled equivalence and validation plan |
| Improve cost or performance | Current resin, cycle, scrap, tooling and quality data | Changes with benefits, risks and trial requirements separated |
| Introduce recycled or lower-impact material | Product duty, content target and traceability needs | A measurable route that still meets product requirements |
Build a product dossier before the show
Prepare the part drawing or package structure, dimensions and tolerances, appearance surfaces, colours, joining features, contact conditions, operating temperature, mechanical and chemical exposure, expected life, annual and peak volume, target cycle, inspection method, packaging and target cost. Add the current material grade, mould status, process window, recurring defects and an approved sample if the product already exists.
Mark each item as fixed, negotiable or still unknown. A wall thickness may be fixed by geometry while resin family, gate position or surface texture remains open to optimisation. Regulatory and customer requirements should be tied to the actual application and destination market. This gives suppliers a clear basis for proposing evidence without asking them to make the buyer’s compliance decision.
For transfer projects, define what “equivalent” means. Equivalence may require more than a generic polymer name: the comparison can include the exact grade or an approved alternative, filler and additive package, colour system, key mechanical or thermal properties, processing behaviour, appearance, odour or contact requirements, test method and retained reference sample.
Connect material, mould, machine and processor
Ask material suppliers to identify the proposed commercial grade, manufacturing source, property and processing data, drying or handling needs, colour or additive system, lot-release approach, traceability, supply continuity and change-notification practice. Application examples can guide questions, while the buyer’s own part trial remains the stronger evidence for the intended use.
Mould discussions should use the same part and material basis. Review cavity number and balance, shrinkage assumptions, steel and heat treatment, gate and runner, cooling, venting, ejection, inserts, texture, sensors, expected tool life, spare inserts, maintenance, trial stages and ownership of the design and physical tool. Record which design inputs still depend on material or machine confirmation.
Machine and auxiliary-equipment conversations then need the proposed resin and mould conditions. For injection moulding, compare shot and plasticising capacity, pressure and control, platen and tie-bar limits, mould services, temperature control, drying, conveying, dosing, robotics, inspection and scrap handling. Extrusion, film or blow-moulding projects need their own output, die, cooling, thickness control, winding, trimming and material-change requirements.
The processor connects these decisions in daily production. Clarify who owns design for manufacturability, material approval, mould trials, parameter release, first-article inspection, process monitoring, preventive maintenance and control of later changes. If different suppliers provide resin, masterbatch, mould, machine and automation, assign a named owner to every interface.
Use a controlled part trial
Define the trial before samples are produced. Record the material grade and batch, moisture or preparation condition, colour and additives, mould revision, machine configuration, process settings, cavity identification, cycle definition, sampling plan, conditioning time, measurement method and acceptance criteria. Hold these inputs constant when comparing alternatives, or make each difference visible in the record.
Inspect parts from startup, stable production and the end of the run. Depending on the product, record dimensions, weight, appearance, colour, surface defects, warpage, shrinkage, flash, short shots, weld lines, mechanical results, leak or functional tests, cavity variation, cycle stability, scrap and operator intervention. A small number of selected samples may establish feasibility; longer stable output is needed to support a production-capability decision.
Separate the evidence by source. Supplier data sheets describe a material under stated tests; laboratory samples show selected properties; an exhibition demonstration shows a configured process; and production on the proposed tool and equipment shows how the chain behaves for the buyer’s part. Each can be useful without being treated as interchangeable.
Keep the approved sample, inspection report and process record linked to one revision. When tuning is still required, list the open issue, responsible party and repeat trial. This prevents a visually good show sample from becoming an undefined reference that cannot be reproduced later.
Check the production system behind the proposal
A supplier or processor visit is most productive when it closes a specific risk. Confirm what work is performed at the proposed address and which legal entity will contract. For materials, relevant checks may include raw-material control, mixing or compounding, production route, laboratory capability, lot release, retained samples, traceability and change control. For moulds, review design release, machining, purchased components, fitting, measurement, trial equipment, corrections, tool records and maintenance support.
For machinery and automation, follow the offered configuration through engineering, assembly, software and parameter control, calibration, safety checks, testing, factory acceptance, packing, installation planning, training, spares and service. For a processor, trace one comparable part through incoming material, storage and drying, setup, production, in-process checks, nonconforming control, release and packing. Any outsourced critical step should appear in the responsibility map.
Commercial comparison should use the same approved product and production assumptions. Separate resin and additives, mould and spare inserts, base machine, auxiliaries, automation, inspection, trial materials, modifications, freight, installation, commissioning, training, recommended spares and service. Record capacity and yield assumptions, lead times, excluded work, payment stages, warranty start and the commercial effect of changes after approval.
Make circularity part of the product decision
For recycled, mass-balance, bio-based or other lower-impact proposals, define the claim being considered and the evidence needed for the destination market. Record material source and composition, recycled-content basis, traceability, batch consistency, contaminants, colour and odour limits, processing changes, scrap route and the properties that still need to meet the product specification.
Compare the circular option through the same part, trial and acceptance route as the conventional material. A useful decision matrix connects each product requirement to the proposed grade, mould and machine assumptions, processor, evidence obtained, remaining trial, approved revision, supply or service risk, quoted scope and next owner. CHINAPLAS then becomes a place to build a production route, not merely to collect separate material and equipment options.
