Sealing Is Everything for Oil
Engine oil caps are not about beauty. They are about sealing. A leak means a big problem. Taizhou KENI Mould Co., Ltd. designed this product for tough lubricant packaging. The main diameters are Φ38mm and Φ42mm. The thread pitch is 2.2mm. This is coarser than water caps. It ensures the cap stays tight after tightening. The sealing lip wall thickness is 1.0 to 1.3mm. We pressure-test every design. The seal withstands at least 0.15MPa. This prevents leaks during long transport and warehouse storage. Cap weight is 6 to 9 grams. Cycle time is 10 to 14 seconds per shot. This engine oil cap mould fits 220T to 280T injection machines. You get a robust seal that customers trust.
100% Inspection on Sealing Structure
We treat sealing as the highest priority for this product. Every sealing lip is inspected. Wall thickness uniformity is kept within ±0.05mm. We test sealing pressure per batch. We reject any parts that fail. Our quality department checks all dimensions. Flash is controlled at ≤0.01mm. We use premium steel for cavities and cores. Hardness meets our standard. Mold life exceeds 1,000,000 shots. We accept third-party inspections. During production, we send you progress updates. If any problem occurs, we coordinate quickly. After delivery, we follow up regularly. This engine oil cap mould is built for high reliability.
