If you're sizing up Enex Engineering for a job, the answer is probably here. If it's not, send the question with the drawings — we'll come back to you within 24-48h.
How to send a job, what to include, how fast you'll hear back, and what the quote actually covers.
24-48 hours for most jobs. Most quotes are returned the same day if drawings arrive before noon AWST. Multi-part assemblies may take a little longer — we'll email back within a few hours to acknowledge and confirm timing.
A drawing or 3D model in any format (STEP best, PDF fine), the quantity, target lead time, and any spec on material, tolerance, surface finish, heat treatment or certs. If you don't have all of that, send what you have — we'll come back with questions.
STEP, IGES, DWG, DXF, PDF, JPG, PNG, ZIP. Hand sketches are fine for simple parts. Native SolidWorks, Inventor and Creo files welcome.
No. A one-off prototype runs through the same shop as a 5,000-part production batch. We quote one part the same way we quote ten thousand.
Yes. The quote is the price. It only changes if you change the spec, if the drawing has missing information that surfaces during programming, or if a material price moves materially between quote and order — and in those cases we come back to you before machining anything.
Reply to the quote email with a PO or written approval. We'll send back an order acknowledgement with start date and committed dispatch date. New customers can pay by EFT or credit card on first order; account terms available after first job.
Yes — on request, before drawings are uploaded. Drawings are treated as commercial-in-confidence by default regardless.
What's in the building, what envelope we can machine, and how tight we can hold.
Three CNC lathes (max turning Ø 450 mm, 1,000 mm bed length), three CNC machining centres (envelope X 1,280 × Y 600 × Z 600 mm, with 4-axis trunnion on one of the mills), two Wire EDM machines (a Seibu — the first Seibu wire-cut EDM in Australia; Seibu invented the wire-cut machine — and a Sodick with 300 mm Z-height), plus a manual lathe, a surface grinder and a laser engraver for in-house part marking. Full inventory on the about page.
Maximum turning Ø 450 mm, 1,000 mm bed length on our CNC lathes.
X 1,280 × Y 600 × Z 600 mm across three machining centres, with 4-axis trunnion on one of them.
±0.01mm is routine on turned bearing surfaces. Wire EDM holds below 0.005mm in hardened steel. Tighter is possible — talk to us before quoting and we'll confirm what's realistic for the geometry and material.
Currently 4-axis. For complex 5-axis geometries we either reposition or partner with a 5-axis shop and finish-machine in-house. Tell us upfront if 5-axis is critical and we'll be straight about whether we can run it economically.
No — welding and fabrication aren't done in-house. We focus on CNC machining; welded assemblies are coordinated through partner shops.
What we machine, how we source it, and what we don't do.
4140 PG bar (heat-treated, 28-32 HRC), 4140 hollow bar (E470), 316 and 304 stainless (round and sheet), bronze C932 and C954, brass C360, aluminium 6061 and 7075, mild steel. Material is sourced per job from Perth distributors.
Yes. Most non-exotic materials arrive within 5 working days through our regular suppliers. Duplex stainless, Inconel, titanium, tool steels — talk to us; we'll source and quote together.
Yes — common for production customers with their own qualified supply chain. We'll machine to your supplied bar and pass back any offcuts.
No — we use accredited Perth-based heat treaters, who can take parts up to 62 HRC (through-hardened, induction, nitride). They sit in the lead time. For 4140 PG (pre-hardened) work, the bar arrives heat-treated and machining is straight-through.
Outsourced to certified Perth providers — zinc, hard chrome, anodise, powder coat, electroless nickel. We manage the whole job and you get one PO, one delivery.
What documentation we supply, what audits we hold, and what production-customers expect.
Yes. EN 10204 3.1 mill certs supplied with every job that requires them. Heat-number traceability on critical materials.
Yes. First-article reports with material certs and dimensional summary, standard for production-run customers. Format flexible — we can match your AS9102, PPAP-style or in-house template.
Formal NCR process. 8D-style root-cause reports available on request for production customers. Containment, corrective action and verification logged against the customer-specific NCR number.
Realistic timelines from approved PO to dispatched part.
5-10 working days from approved PO, depending on geometry and material. Common-material jobs run faster; specialist or heat-treated jobs sit toward the longer end.
First article in 2-3 weeks. Full batch follows on a schedule agreed at PO — most production customers run on 2 to 8 week call-off intervals. We'll commit to dispatch dates at order acknowledgement and hold them.
Yes. Same-week and same-day rush work happens, especially for mine-site breakdowns. Tell us upfront — we'll be straight about whether we can fit it without dropping someone else's promised date.
3-7 working days typically. EDM jobs run in batches; if your geometry fits a current setup the part can move faster.
Where parts go, how they get there, and what it costs.
Daily Perth metro courier. Weekly direct freight to Karratha, Port Hedland, Kalgoorlie, Geraldton, Adelaide and Darwin. On-demand to remote mine sites Australia-wide.
Karratha typically 38h after pickup. Port Hedland 48-60h. Both run on weekly direct services with regular departure days; we'll book onto the next service that fits the dispatch date.
Most jobs land in Kalgoorlie 24-48h after dispatch from Malaga. Daily depots in town, regular services to Coolgardie, Leonora and the Eastern Goldfields satellite towns.
Yes — collection from Malaga 7am-5pm Mon-Fri, by appointment. Many Perth metro customers collect themselves to save freight.
Occasionally — typically to project sites in PNG, Indonesia or NZ. Air-freight or sea-freight, EXW Malaga as standard. Get in touch for a quote that includes export packaging.
The 79-SKU catalogue for heavy-haulage trailer fleets.
Heavy-haulage low-loader, steerable, drop-deck, skel and tipper trailers from the major Australian and overseas manufacturers. Direct-fit to original-equipment specs. Browse the catalogue →
Lead time varies by part and current production load. Send the part number and we'll come back with current availability within 24-48 hours.
Send a worn part or photos with measurements. We reverse-engineer and machine the replacement, typically 5-10 working days. More on reverse engineering →
No — every part in the catalogue is Enex-machined to original-equipment specs. Direct-fit replacement, often at a fraction of OEM cost and lead time, especially for older and obsolete trailer models.
Worn parts, obsolete OEM parts, parts with no drawings.
Yes — that's a core service. Send the worn part or clear photos with measurements; we measure, model in CAD and machine the replacement.
No. The whole point of reverse engineering is that the drawings are gone (or the OEM has moved on). We produce drawings as part of the job and can supply them to you on completion.
5-10 working days from worn part to delivered replacement, depending on geometry and material. Faster on simple geometries that don't need heat treatment.
Often workable — we can scale from a mating part, infer from photos of an intact unit, or reconstruct from witness marks. Bring what you have, including any partial drawings or specs from the OEM.
Yes — drawings produced for your job belong to you. We retain a working copy for repeat orders unless asked to delete.
