射出成形プロセスには、成形前の準備が含まれます, プラスチック部品の射出プロセスと後処理.
成形前の準備には、原材料の外観の検査と技術的特性の決定が含まれます, 予熱と乾燥, 射出成形機バレルの洗浄, インサートの予熱と離型が困難な場合の離型剤の選択. 金型を予熱する必要がある場合があります.
成形中, powdered or granular materials are fed from the hopper into the high-temperature barrel for melting and plasticizing to become viscous fluid melt, and then injected through the nozzle at a high speed into the closed mold at a lower temperature under the high pressure of the plunger or screw. The melt fills the cavity under pressure and is compacted. After a period of holding pressure, the plunger or screw returns. この時点で, the melt may flow back from the cavity to the gating system. 型は一般的に雌型で構成されています, the mold can be opened and the product can be removed from the mold cavity.
After the plastic is heated and plasticized in the barrel of the injection machine, it enters the mold cavity through the pouring system of the mold. The final cooling process is called the pouring process.
The injection process usually includes feeding, plasticizing, 充填, ホールディング, reverse flow, cooling and demoulding.
- addition
The powder is added to the hopper of the injection machine.
- plasticizing
The plastics are added in the barrel to make it melt from solid particles and have good plasticity. This process is called plasticization.
- mold filling
The plasticized melt is pushed to the front of the barrel by the plunger or screw, and is filled with the cavity through the nozzle and mold pouring system. This stage is called filling.
- guaranteed pressure
When the melt in the mold is cooled and contracted, the plunger or screw forces the melt in the barrel to replenish the mold continuously, thus forming a complete and compact plastic part. This stage is called packing.
- reflux
At the end of packing, the plunger or screw recedes and the pressure in the cavity is relieved. 現時点では, the melt pressure in the cavity will be higher than that in front of the gate. If the gate has not been frozen, the melt in the cavity will return to the pouring system through the gate. This process is called backflow.
Reverse flow causes plastic parts to produce shrinkage, deformation and loose texture defects. If the gate is frozen when the pressure is over, there will be no backflow phenomenon.
- ベンダーは、製品の一部を提供する栄光の倉庫である必要はありません。
The cooling process of a plastic part in a mold refers to the whole process from the time when the plastic melt at the gate is completely frozen to the time when the plastic part will be pushed out of the mold cavity. 実際には, the cooling process begins with the injection of plastic into the mold cavity, which includes the period from the completion of filling, the beginning of packing to the time before demoulding.
- Demolding
When the plastic parts are cooled to a certain temperature, the mold can be opened, and the plastic parts are pushed out of the mold under the action of the pushing mechanism.
The key parameters that determine the molding quality of products are temperature, 時間, 圧力, speed and position.
