Inside our plants

Vertical integration, end to end

Injection, stretch-blow and extrusion-blow, plus in-house printing and an on-site mold shop — the whole chain sits under our roof, so nothing critical is outsourced.

Injection Molding

Injection Molding

16 injection-molding machines produce PET pre-forms, caps, pumps and closures with tight neck tolerances.

Stretch Blow

Stretch Blow

PET pre-forms are stretch-blown into crystal-clear bottles with even wall distribution and high strength.

PET bottles · high clarity
Extrusion Blow

Extrusion Blow

30+ automatic lines extrusion-blow PE/PP bottles in a single step — from soft squeeze to rigid cleaners.

HDPE / PP · one-step

How a bottle is made

Two proven production flows

PET runs a two-stage pre-form + stretch-blow route for clarity and strength; PE/PP is extrusion-blown in a single step for speed and chemical resistance.

Resin is dried at 170–180°C for 3–4 h; masterbatch at 100–120°C for 2 h — controlled moisture is what keeps walls clear and strong.

In-house mold shop
In-house tooling

Your private mold, built & kept in-house

Our on-site mold shop designs, cuts and maintains tooling — so a private bottle stays exclusively yours, iterations are fast, and repairs never stall your production.

  • Mold numbering by material: PET tools = SJT, PE tools = SJE
  • Design → sample → sign-off before mass production
  • On-site maintenance keeps lead times reliable
  • Tooling stays confidential and exclusive to your brand
