Consumer Goods Injection Moulding: Housings, Toys & Cosmetic Parts
Consumer goods moulding lives and dies on two things: how the part feels in the hand, and whether it survives the retail shelf. Housings for appliances, personal care devices, toys, cosmetic packaging and household products all share the same underlying decisions — material against drop and chemistry, finish against fingerprints, colour against brand standard — plus a volume profile that rarely justifies commodity tooling at launch. That profile, prototype through market test to proven series, is exactly where Nordmould positions.
Which materials cover the consumer spectrum?
| Material | Typical consumer parts | Why it is chosen |
|---|---|---|
| ABS | Appliance housings, toy blocks, device shells | Impact, stiffness, excellent surface for paint or texture |
| PP | Hinged containers, kitchenware, chemical-exposed parts | Living hinges, detergent resistance, low cost |
| PC/ABS | Premium housings, handheld devices | Impact plus heat resistance, V-0 grades available |
| PMMA / SAN | Cosmetic jars, transparent covers, display parts | Clarity and gloss, scratch resistance |
| TPE / TPU | Grips, seals, bumpers, wearable contact parts | Soft touch, grip, over-mould bonding |
ABS remains the default housing material — the ABS page covers its processing and finish behaviour. Where the design hinges — literally — PP is the only serious candidate. Transparent cosmetic parts trade up to PMMA for clarity that survives retail handling.
Toys: what does EN 71 actually demand?
EN 71 splits into parts that matter differently to a moulder. EN 71-1 (mechanical and physical) drives design: no small detachable parts for under-3s, no sharp edges after impact testing, no pinch points — geometry the designer owns but the moulder's ejection and parting-line quality can make or break. EN 71-2 (flammability) constrains material choice on disguise costumes and textiles more than rigid parts. EN 71-3 (migration of certain elements) is the material-level requirement: pigments and stabilisers must stay within migration limits, which means toy parts should run on documented grades with compliant colourants, not generic regrind blends. CE marking and the test programme remain the toy manufacturer's legal responsibility; Nordmould supplies material certificates and consistent, flash-free mouldings as the evidence base.
Personal care and cosmetics: chemistry meets cosmetics
Razors, brushes, dispenser housings and cosmetic jars face a distinctive combination: surfactants, oils and alcohols attacking the polymer while the surface must stay showroom-clean. Styrene-acrylic combinations craze under surfactant exposure; PP shrugs it off but scratches. Transparent cosmetic parts run PMMA or SAN for clarity, with wall sections kept uniform to avoid visible sink on gloss faces. Colour is a brand asset here — specify against a physical master plaque and control it per batch, as covered in the colour matching and masterbatch guide.
Surface finish and texture: the perceived-quality lever
Texture choice sets perceived quality and tooling cost together. A fine VDI 18-24 matt grain hides fingerprints, flow marks and minor sink for almost no tooling premium; deep leather grains (VDI 33-39) give grip but demand extra draft — roughly 1° per 25 µm of texture depth — or the part drags on ejection. High-gloss cosmetic fronts need polished steel, immaculate packing discipline and uniform walls, because every sink mark shows. Logos and fine engraving are cheapest raised from the surface. The surface finishes guide maps the standard grades to appearance and cost.
Two-shot soft-touch: when is it worth it?
Two-shot moulding injects a rigid substrate (ABS, PC/ABS, PP) and a TPE second shot in one cycle, bonding them chemically into an integrated grip, seal or bumper. The result beats assembled grips on durability, waterproofing and feel — toothbrushes, power-tool handles and personal care devices are built this way. The cost is real: two-shot tooling, a matched material pair, and a machine with a second injection unit. Below a few tens of thousands of parts, insert over-moulding or assembled TPE sleeves usually win; the two-shot guide details the trade-off, and the TPE material page covers substrate bonding.
Design for assembly and drop
Consumer parts are assembled parts: snap-fits instead of screws wherever service access is not needed, bosses proportioned for self-tappers where it is, and a tolerance stack checked across mating shells before tooling. Drop performance comes from corner radii, ribbing strategy and material choice — not from thicker walls, which add sink and cycle time. The snap-fit design guide and the ribs and bosses design rules cover the geometry; electronics-heavy products should also review the electronics enclosures page.
What should buyers bring to the RFQ?
Consumer projects quote fastest when the enquiry states the cosmetic specification (texture grade, gloss level, colour standard), the compliance context (EN 71 for toys, skin-contact or food-adjacent use), annual volume and launch timeline, and any assembly strategy already decided — snap-fits, screws, over-moulding. Two shots or one, texture depth and draft, colour-matching route and packaging of the moulded parts themselves all move price and lead time, and all are settled fastest inside the free DFM review rather than across a month of emails. Consumer goods are the core of Nordmould's low-volume model, and the DFM note comes back within an agreed timeframe.
Volumes and economics for consumer launches
Consumer launches reward staged commitment: 100-500 pieces for market tests and crowdfunding, aluminium bridge tooling in the low thousands, then production steel once sales data exists. Use 100 pieces and €3,000 tooling only as illustrative planning references; the written quotation confirms the actual minimum quantity, tool specification and prices.

Frequently asked questions
Which plastics are most common in consumer products?
ABS for housings and appliance shells, PP for living-hinge and chemical-exposed parts, PC/ABS where impact and heat demands rise, PMMA and SAN for transparent cosmetic components, and TPE for soft-touch over-moulds. Selection follows drop performance, chemical exposure, and the cosmetic specification.
What does EN 71 require for injection-moulded toys?
EN 71 is the European toy safety standard family: EN 71-1 covers mechanical and physical properties (small parts, sharp edges, impact), EN 71-2 flammability, and EN 71-3 migration of certain elements. CE marking and testing are the toy manufacturer's responsibility; the moulder's contribution is documented, compliant materials and consistent, burr-free parts.
How is colour consistency managed across production runs?
Colour is specified against a master standard (Pantone, RAL, or an approved physical plaque), matched with a masterbatch or pre-coloured compound, and controlled per batch. Let-down ratio, regrind content and processing temperature all shift shade — lock them in the specification and approve a colour plaque before series production.
What is two-shot soft-touch moulding?
Two-shot moulding injects a rigid substrate and a soft TPE second shot in one machine cycle, producing an integrated grip or seal with a genuine chemical bond. It beats assembled grips on durability and feel, but requires two-shot tooling and matched material pairs — worth it at sustained volumes, overkill for short runs.
What surface finishes can be moulded directly into the tool?
Texture is etched into the mould steel: fine matt grains (VDI 18-24) hide fingerprints and handling marks, medium grains (VDI 27-33) give grip, high-gloss polish suits cosmetic fronts. Texture needs draft — roughly 1° per 25 µm of texture depth — so finish choice belongs in the DFM review, not after tooling.
What volumes suit consumer product launches at Nordmould?
Use 100 pieces only as an illustrative batch-planning reference; the actual minimum quantity and manufacturing route are confirmed in the written quotation. Aluminium bridge tooling keeps entry cost low; production steel follows when volumes prove out. Consumer goods are the core low-volume use case the service was built around.
