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 \u0627\u0646\u0679\u06cc\u06af\u0631\u06cc\u0679\u0688 \u0628\u0644\u0648 \u0645\u0648\u0644\u0688\u0646\u06af \u0645\u0634\u06cc\u0646<\/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 \u062c\u0627\u0626\u0632\u06c1 \u0644\u06cc\u062a\u06d2 \u0648\u0642\u062a \u0627\u06cc\u06a9 \u0642\u062f\u0645 \u0627\u0646\u062c\u06a9\u0634\u0646 \u0628\u0644\u0648 \u0645\u0648\u0644\u0688\u0646\u06af \u0645\u0634\u06cc\u0646 \u062a\u06a9\u0646\u06cc\u06a9\u06cc \u0648\u0636\u0627\u062d\u062a\u06cc\u06ba<\/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 \u06a9\u0627\u0633\u0645\u06cc\u0679\u06a9 \u067e\u06cc\u06a9\u06cc\u062c\u0646\u06af \u06a9\u06d2 \u0644\u0626\u06d2 \u0627\u06cc\u06a9 \u0642\u062f\u0645 \u062f\u06be\u0686\u06a9\u0627 \u0645\u0648\u0644\u0688\u0646\u06af \u06a9\u0627 \u0633\u0627\u0645\u0627\u0646<\/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
