Что такое полистирол (Пса) Инъекционное формование?
Полистирол (Пса) is a widely used thermoplastic polymer made from styrene monomers, celebrated for its clarity, доступность, и простота обработки. Инъекционное формование is a manufacturing process that melts plastic pellets, injects the molten material into a custom mold cavity, cools it, and ejects the finished part. Combined, PS injection molding produces consistent, high-quality components for diverse sectors, leveraging PS’s unique traits to meet various application demands.
Key Definitions & Process Overview
| Термин | Определение |
| Полистирол (Пса) | A thermoplastic with two main forms (rigid and foam); known for clarity, легкий вес, and low cost. |
| Инъекционное формование | A cyclic mass-production process: PS pellets → melted → injected into mold → cooled → ejected (repeats for efficiency). |
| Mold Cavity | The hollow space in a mold that shapes the final PS part; can have 1–128 cavities for high-volume output. |
Material Properties of PS
PS’s distinct properties make it ideal for injection molding. Below are the most critical traits for manufacturers and buyers:
- Clarity and Transparency: Amorphous PS (general-purpose PS) имеет 90% light transmittance—comparable to glass, making it perfect for visible packaging.
- Плотность: 1.04–1.06 г/см ним (легкий вес, reducing shipping costs and part weight for consumer goods).
- Точка плавления: 140–180 ° C. (low melting temperature, lowering energy consumption during molding).
- Бриттлис: Rigid PS is brittle (воздействие сила: 1.5–2.5 kJ/m²), but can be modified with rubber additives for toughness.
Ease of Processing: Low viscosity when melted, filling complex mold details easily—ideal for intricate parts.

The PS Injection Molding Process: Step-by-Step Excellence
PS’s unique melting and cooling properties require a optimized process to avoid defects like warping or cloudiness. Our workflow ensures consistent quality while maximizing efficiency.
Шаг 1: Материал подготовка
- Pellet Selection: Choose between general-purpose PS (GPPS, для ясности), high-impact PS (БЕДРА, за стойкость), or foam PS (Поступок, for insulation).
- Additive Blending: Mix PS pellets with добавки (UV stabilizers for outdoor use, colorants for branded parts, rubber modifiers for impact resistance).
- Сушка: PS absorbs minimal moisture, but we dry pellets at 60–70°C for 1–2 hours to prevent surface defects (НАПРИМЕР., bubbles in transparent parts).
Шаг 2: Mold Design
- Clarity Considerations: Molds for transparent PS parts have polished surfaces to maintain clarity (no scratches or texture that reduces light transmittance).
- Cooling Optimization: Molds include uniform cooling channels to prevent warping—critical for thin-walled PS parts (НАПРИМЕР., упаковка).
- Prototype Testing: We 3D-print mold prototypes first to validate design (reduces costly revisions and ensures part functionality).
Шаг 3: Injection Parameters (Critical for PS)
PS’s low melting point and viscosity require precise parameter tuning. Below are our standard settings for GPPS (the most common PS grade):
| Параметр | Ideal Range for GPPS | Цель |
| Barrel Temperature | 160–200°C | Melts PS evenly without degradation (higher temps cause yellowing). |
| Давление впрыска | 40–100 MPa | Fills mold cavities completely (critical for intricate details like packaging logos). |
| Время охлаждения | 10–25 seconds | Prevents warping; balances speed and part stability (shorter for thin parts). |
Шаг 4: Post-Molding Operations
After demolding, PS parts may undergo:
- Обрезка: Удаление лишнего пластика (вспышка) with automated tools (critical for clear parts to maintain aesthetics).
- Сборка: Joining parts via adhesives or snap-fits (for complex components like consumer product enclosures).
Осмотр: Final QC checks for clarity, Точность размеров, и качество поверхности (100% inspection for medical or food-contact parts).
Материалы: Choosing the Right PS for Your Project
Not all PS is the same—selecting the right grade ensures your parts meet performance, расходы, and aesthetic goals. We offer a full range of PS materials, plus recycled options.
