Common defects of damaged caps include stripped cap threads, cracked cap tops, chipped cap edges, broken tamper-evident rings and worn internal threads. There are mainly four categories of causes: excessive torque, misalignment, inherent defects of bottle/cap raw materials, and improper material/high pressing force of the capping head.

As a professional manufacturer and factory from China, the core of selecting an automatic capping machine is matching your production conditions, meeting capacity requirements, and ensuring capping precision and stability. Meanwhile, take versatility, failure rate and long-term maintenance costs into consideration. There are many types of machines on the market with widely varying parameters. Blind procurement may lead to common issues such as cap jamming, inconsistent tightening torque, liquid leakage and poor compatibility. Below is a multi-dimensional selection guide covering pitfalls for beginners, mass production adaptation and long-term operation needs.

Summary: Seals with the same structure, cylinder bore and valve type may be interchangeable. Most complete machine parts from different brands cannot be directly replaced. Blind mixing of parts is not recommended.

Dual‑Head Tracking Filling Machine ‑ In‑Depth Technical Brief Full Name：Dual‑Servo Dual‑Head Follow‑Type Filling Machine Core Technology: Electronic cam dynamic follow‑up. Bottles keep running on the conveyor without stopping or blocking. Filling heads travel at the same speed as bottles and complete filling dynamically, which differentiates it from conventional fixed‑position stop‑and‑fill fillers.

The automatic liquid pre‑made pouch packing machine adopts pre‑fabricated pouches. Compared with roll‑film form‑fill‑seal machines and semi‑automatic filling‑sealing equipment, its advantages are reflected in finished packaging quality, flexible production, hygiene & safety, automation level, and compatibility with materials and pouch types:

Applicable for piston‑type, gear‑pump, peristaltic‑pump and vacuum automatic liquid filling machines Safety Precaution: Cut off power supply and air source before maintenance. Allow hot‑material equipment to cool down. Do not wash electrical components directly with water. For food & pharmaceutical grade units, perform cleaning in compliance with GMP requirements. Maintenance levels: Daily Maintenance, Weekly Maintenance, Monthly Maintenance, Quarterly Maintenance, including reference replacement cycles for key wearing parts.
