From first conversation to first shipment — in 1 to 3 weeks.

From discovery call to ongoing partnership.

1. 01

   Discovery call

   Week 1 · 30 minutes · no commitment

   Schedule a call with Delta sales engineering. We scope your application, target volumes, neck finish preferences, climate + distribution conditions, and timeline. You'll talk to either Mohamed Hisham (Chief Commercial Officer) or a senior application engineer — not a generic account rep.

   What to prepare

   • Bottle target (fill volume, height, OD, application: water/CSD/juice/dairy/oil/detergent)
   • Estimated annual volume (units/year)
   • Distribution geography (domestic, regional, export)
   • Existing capper + filling line model (helps validate neck-finish compatibility)
   • Any sustainability targets (rPET %, lightweighting program)

   Self-serve preparation tools: Try the preform bottle advisor first — get a shortlist of compatible SKUs before the call. Use the preform engineering tool to check stretch ratios for your target bottle.

2. 02

   Sample evaluation

   Week 1 · samples shipped within 5 business days of request

   After the discovery call, Delta ships samples of the candidate preform + matching closure SKUs to your plant. Your QC team validates against your bottle target using industry-standard methods: drop test (ASTM D2463), top-load (ASTM D2659), ESCR (ASTM D1693 + ISO 22088), neck-finish gauge, dimensional CMM. We provide our own in-house test results for comparison.

   What you receive

   • 50-100 preform samples (depending on neck finish family and cavity availability)
   • Matching closure samples (50-100 caps)
   • Delta's in-house test results for the same sample lot
   • Spec sheets (PDF + .xlsx)
   • Suggested capper torque windows for your specific neck finish + closure combination

   While samples are evaluated: Your QC engineer can use the defect lookup library as a live reference — 102 documented defects with diagnostic flows.

3. 03

   Documentation review

   Week 1 · documentation delivered within 1 week of request

   Delta provides full audit-ready documentation. Our turnaround commitment: documentation requests fulfilled within 1 week — most preform/closure suppliers measure this in months. This is a deliberate competitive moat for inland and export markets where procurement teams are scored on supplier audit response times.

   Documentation included

   • FSSC 22000 V6 certificate (recertified annually)
   • ISO 9001:2015 certificate
   • Food-contact compliance (EU Reg 10/2011, FDA 21 CFR, GSO 2231)
   • Migration test certificates (per food simulant)
   • COA (Certificate of Analysis) sample for the proposed material lot
   • rPET supplier compliance letters (if rPET program)
   • Cavity-level traceability example for IMD closures
4. 04

   Supplier audit (optional)

   Week 2 · scheduled at customer's pace

   For multinationals and customers with strict supplier-quality programs, an on-site audit at the Delta plant (New Salhiya City, Sharkia) is standard. We host audits on a rolling schedule — typical lead time 2-3 weeks from request to audit day. Tier-2 and emerging customers often skip this step or substitute a virtual audit.

   Audit scope (typical)

   • Production line walk-through (injection + IMD inspection station)
   • QC laboratory tour (in-house testing capabilities, NIST-traceable calibration)
   • Traceability documentation review (batch-level for preforms, cavity-level for closures)
   • Material sourcing + storage (food-grade segregation, FIFO)
   • Q&A with founders / second generation leaders (typically Hisham Abd El Hakim or Mohamed Hisham)
5. 05

   Approved-supplier status + commercial terms

   Week 2 · the gate

   Customer issues approved-supplier or qualified-supplier status based on samples, documentation, and audit (if conducted). Commercial terms finalized: per-unit pricing, MOQ, lead times, payment terms (typical: 30-60 days net, LC for export), INCOTERMS (typical: FOB Damietta for sea freight, EXW for inland), packaging spec (bulk bags vs cartons), and quality clauses (acceptance criteria, AQL, defect rate caps).

   Outputs of this step

   • Signed supply agreement (typical term: 1-3 years with renewal)
   • Customer's approved-supplier ID assigned at Delta
   • Production planning calendar locked (capacity reserved)
   • Quality SLA documented (acceptance criteria, complaint workflow)
6. 06

   First production order

   Weeks 2–3 · first production order placed

   First PO placed. Delta's production planning team (under Moustafa Hisham, COO/CTO) schedules the run. Material sourcing, cavity assignment, in-process QC checkpoints, and shipping logistics are coordinated. First-order lead time is longer than steady-state (4-6 weeks vs 2-3 weeks ongoing) because we burn-in your specific bottle target on the actual cavities.

   What happens during these weeks

   • Week 1: PO acknowledged, materials sourced, cavity assigned
   • Weeks 2-3: Production run, IMD inspection on every closure, QC sampling per AQL plan
   • Week 4: COA + COC issued, packaging, sea freight booking
   • Weeks 5-6: Transit — sea freight from Damietta, road for MENA inland
7. 07

   First shipment + on-site line trial

   Week 3 · Delta application engineer on-site for first run

   Containers arrive at customer plant. A Delta application engineer travels on-site for the first production run on your filling line. We dial in capper torque windows for your specific capper + closure combination, tune in-process QC against your acceptance criteria, and troubleshoot any issues that surface during the first 24-72 hours of production.

   On-site engineer activities (typical 3-5 days)

   • Capper torque window calibration (per-SKU: PCO 1881 14-22 in-lbs, PCO 1810 16-26, 32/15 8-14, 38mm 12-20)
   • Starwheel centering verification (less than 0.5mm offset tolerance)
   • Removal torque sampling (target SD less than 15% of mean)
   • First-shift defect dashboard review with customer QC
   • Handover document with all calibrated settings, for future shift changes

   Ongoing program support

   Ongoing · quarterly business reviews

   Once you're in steady-state production, the partnership shifts from onboarding to ongoing program support. Quarterly business reviews cover production volumes, quality metrics, market changes, and any new SKU scope. Your QC team has direct access to Delta's defect lookup library and AI tools. Quality escalations skip the support-ticket queue and go directly to a founder or second-generation leader — owner-led accountability, not a customer-service relay.

   What ongoing support includes

   • Quarterly business review (QBR) — typically 60-90 minutes, on-site or video
   • Live access to the defect lookup library and AI tools (no login, free to your whole team)
   • Quality escalation path: customer QC → Delta application engineer → second-gen leader → founder (no support-ticket queue)
   • Documentation refresh — annual FSSC 22000 V6 recertification, ISO renewal, updated COA/migration tests
   • Optional: co-development on new SKUs, lightweighting programs, rPET migration
