Common requirements and difficulties in appliance moulding

Appliance volumes are high and appearance standards are strict, while unit cost and certification cycles constrain the choice. Selecting a material means trading these conditions against one another.

Documents and support we can provide

Test reports and manufacturer documents are available from your sales contact. We check them against the specific grade before sending, and this site does not offer PDF downloads.

Questions from buyers and engineers

The four questions we are asked most often on appliance projects.

Note: these are the common directions. The same part often has several options depending on wall thickness and tooling, and we can help compare flow and shrinkage behaviour before a grade is confirmed.

Requirements & pain points

Common requirements and difficulties in Home Appliances

High volumes and strict appearance demands, constrained by product cost and certification cycles.

01

Colour consistency and appearance

Visible parts are sensitive to colour drift, and variation between batches leads to rejection after assembly. The fix starts with masterbatch formulation, retained samples and batch management, rather than with a single sample.

02

Flame retardancy and appliance certification

Some electrical parts have to meet flame retardancy and safety requirements alongside ROHS and REACH. Whether the raw material comes with the corresponding test documents directly affects audits and shipping schedules.

03

Narrow processing window on thin-wall, large parts

Panels and liners have long flow paths and thin walls. Insufficient flow causes short shots and sink marks, while excessive flow brings flash and stress distortion.

04

Weathering and ageing in long-term service

Parts such as air conditioner grilles and washing machine top covers face heat, moisture or UV for years. Grade and additive system have to match the service environment.

05

Cost pressure and downgrade evaluation

Appliance prices are highly competitive. Replacing a grade with a general purpose material, or moving to a different grade level, is a common route to lower cost, but strength and appearance have to be assessed first.

Recommended materials

Material class	Problem solved	Example parts	Common grades / notes
ABS (general purpose / high gloss)	Gloss, dimensional stability and controlled fit in assembly	TV and monitor housings, control panels, decorative parts	General purpose and high gloss injection grades
ABS (flame retardant)	Meets appliance flame retardancy and electrical safety requirements	Parts around power supplies, switch boxes, internal brackets	Matched to the flame retardancy class of the appliance
HIPS / high impact PS	Balances moulding of large parts, stiffness and cost	Refrigerator liners, air conditioner inner shells, drawers, grilles	General purpose / high impact grades
PP (homopolymer / copolymer)	Chemical and heat resistance with toughness for load-bearing parts	Washing machine tubs, fan blades, sink components	Homopolymer and copolymer injection grades
Masterbatch	Colour consistency and batch-to-batch colour control	Visible parts, identification parts	Made to your colour standard; sample confirmed first

Documents and support we provide

Test reports and producer documents are available on request — we check them against each grade.

SGS / REACH / ROHS test documents

Issued against the specific grade and available on request, for factory audits, shipments and customer reviews.

Grade selection advice

A comparison of flow, impact strength and flame retardancy class against wall thickness, flow length ratio and appearance requirements.

Colour standard and colour matching

Colour standards or small samples are confirmed before matching, and production batches are compared under the agreed light source to reduce disputes over colour drift.

Shipping documents

Certificate of analysis and related documents supplied with the goods where the manufacturer provides them, for incoming inspection and batch traceability.

FAQ

Common purchasing and engineering questions

QWhat is the difference between flame retardant ABS and general purpose ABS, and how much more does it cost?

A flame retardant grade achieves its performance through formulation, which usually changes flow, colour and weathering behaviour, and it costs more. Whether you need it depends on the certification of the appliance and the position of the part. Please ask your sales contact for the specific differences and current pricing.

QWe are only running a small trial batch. Can we buy a small quantity first?

Yes. We arrange small trial quantities for tool trials and process confirmation, and agree the production batch and lead time before volume ordering.

QCan you match a colour to our own colour code?

We can match colour standards and formulate masterbatch to your requirement. An actual colour standard or colour code helps; we confirm with a small sample before the production batch.

QDo we need to re-tune the moulding process after switching material?

Flow and shrinkage differ between grades, so a tool trial before the switch is advisable, with barrel temperature, mould temperature and holding pressure adjusted accordingly. We can help connect you with the manufacturer's processing recommendations.
