一、塑膠射出是什麼？
Plastic Injection（Plastic Injection Molding，又稱射出成型）是最常見的塑膠加工方式之一。透過加熱熔融塑膠顆粒，並將其注入金屬模具中冷卻成型，即可大量生產外觀一致、精度高的零件。
常見應用包含：
醫療器材（血糖機外殼、管件）
汽機車零件（電動機車定子件、車燈外殼）
3C產品（按鍵、外殼）
生活用品（廚房用品、衛浴配件）
二、塑膠射出流程解析
產品設計 – 客戶提供 2D/3D 圖面，需考慮外觀、強度、功能。
模具設計與製作 – 模具品質直接影響產品壽命與精度。
射出成型 – 將塑膠顆粒加熱至熔融狀態，注入模具成型。
冷卻與脫模 – 成品冷卻後自動或手動取出。
品管檢測 – 尺寸測試、外觀檢查、強度測試，確保符合標準。
三、塑膠射出常用材料
不同產品需求，需要選擇不同的塑膠材料：
ABS：韌性佳、適合外殼零件
PC（聚碳酸酯）：透明度高，常用於燈罩、光學件
PP（聚丙烯）：耐酸鹼、食品容器常見
POM：高強度、低摩擦，適合齒輪零件
PMMA（壓克力）：高透明度，可做光學應用
四、選擇塑膠射出代工廠的重點
設備能力：是否具備多噸位射出機、能處理精密件。
模具技術：是否有模具設計、維修能力。
品質管理：是否有完整檢測流程，符合 ISO 或業界標準。
服務彈性：能否支援小量試產、大量量產。
案例經驗：是否有跨產業合作經驗（如醫療、電動機車、電子）。

The Plastic Injection Molding Process
Product Design – Customers provide 2D/3D drawings, considering appearance, strength, and functionality.
Mold Design & Fabrication – The quality of the mold directly affects product accuracy and durability.
Injection Molding – Plastic pellets are melted and injected into the mold cavity to form parts.
Cooling & Ejection – The molded part is cooled and then removed automatically or manually.
Quality Inspection – Dimensional measurement, visual inspection, and performance testing ensure compliance with requirements.
Common Plastic Materials for Injection Molding
Different products require different plastic materials:
ABS: Excellent toughness, suitable for housings and enclosures
PC (Polycarbonate): High transparency, ideal for lenses and lighting covers
PP (Polypropylene): Chemical-resistant, widely used for food containers
POM (Acetal): High strength and low friction, suitable for gears and mechanical parts
PMMA (Acrylic): High transparency, used in optical applications
