Mastering the art of thick-walled cosmetic packaging with advanced single stage injection stretch blow molding machine technology.<\/p>\n<\/div>\n
One-step Injection Stretch Blow Moulding (ISBM) is an elite plastic container forming process engineered for high-precision, demanding hollow plastic products.

There is no intermediate cooling or reheating phase. This leads to profound core advantages:<\/p>\n The mold system, comprising the preform molds, blow molds, and cooling infrastructure, typically employs a rotary multi-station structure. The choice between a 3-station and a 4-station layout is the most critical decision when configuring your \u0622\u0644\u0629 \u0646\u0641\u062e \u0627\u0644\u0642\u0648\u0627\u0644\u0628 \u0627\u0644\u0645\u062a\u0643\u0627\u0645\u0644\u0629<\/strong>.<\/p>\n Process: Injection \u2192 Stretch Blow \u2192 Ejection<\/strong> Process: Injection \u2192 Conditioning \u2192 Stretch Blow \u2192 Ejection<\/strong> Advanced Mold Manufacturing Technology:<\/strong><\/p>\n Below is a closer look at our precision mold wiring and a completed custom mold ready for production:<\/p>\n \u0639\u0646\u062f \u0627\u0644\u0645\u0631\u0627\u062c\u0639\u0629 \u0627\u0644\u0645\u0648\u0627\u0635\u0641\u0627\u062a \u0627\u0644\u0641\u0646\u064a\u0629 \u0644\u0645\u0627\u0643\u064a\u0646\u0629 \u062d\u0642\u0646 \u0627\u0644\u0642\u0648\u0627\u0644\u0628 \u0628\u0627\u0644\u0646\u0641\u062e \u0628\u062e\u0637\u0648\u0629 \u0648\u0627\u062d\u062f\u0629<\/strong>, equipment compatibility is vital.

Deciphering the Mold System: 3-Station vs. 4-Station<\/h2>\n<\/div>\n
<\/p>\nThe 3-Station Configuration<\/h3>\n
\nBy skipping the conditioning station, the 3-station mold allows the preform to move directly from injection to blowing. This results in faster cycle times and a smaller machine footprint. It is highly recommended for standard round water bottles, pharmaceutical vials, and simple cylindrical containers.<\/p>\n<\/div>\n
<\/p>\nThe 4-Station Configuration<\/h3>\n
\nThe 4-station design includes a dedicated temperature conditioning (heat preservation) station. This is the ultimate \u0645\u0639\u062f\u0627\u062a \u0646\u0641\u062e \u0627\u0644\u0642\u0648\u0627\u0644\u0628 \u0628\u062e\u0637\u0648\u0629 \u0648\u0627\u062d\u062f\u0629 \u0644\u062a\u063a\u0644\u064a\u0641 \u0645\u0633\u062a\u062d\u0636\u0631\u0627\u062a \u0627\u0644\u062a\u062c\u0645\u064a\u0644<\/strong>. Thick-walled PETG jars and complex asymmetrical shapes require precise thermal equalization before stretching. The 4th station prevents stress whitening and ensures absolute glass-like clarity in luxury packaging.<\/p>\n<\/div>\n<\/div>\n\n
