Low-pressure moulds belong to high-precision cyclic operation equipment, and daily maintenance and regular inspection directly determine production stability and service life. Most mould premature failures are caused by irregular daily maintenance rather than mould quality problems. Many enterprises only focus on production and ignore maintenance, resulting in gradual mould precision drift, surface wear and structural failure. Xinfeng Machinery formulates standardized daily, weekly, monthly and quarterly graded maintenance specifications for industrial users.
Daily maintenance focuses on cleaning and anti-wear protection. After daily production, clean residual aluminum oxide and sundries on the mould cavity surface, and perform uniform release agent spraying and anti-rust oil coating. This simple operation reduces surface adhesion and dry wear defects by 85%, maintaining long-term cavity smoothness.
Weekly key component maintenance ensures core functional stability. Focus on cleaning vent slot gaps to eliminate exhaust blockage and inspect cooling pipelines for scale and blockage. Regular maintenance of venting and cooling systems avoids 90% of common defects such as casting air holes, porosity and mould overheating deformation.
Monthly precision calibration maintains product dimensional accuracy. Inspect and calibrate mould positioning pins, guide sleeves and ejection systems to correct tiny tolerance drift, controlling overall mould assembly tolerance within ±0.01mm and ensuring consistent product size in long-term batch production.
Quarterly and annual deep maintenance delays mould aging. Quarterly heat stress relief maintenance eliminates accumulated cyclic temperature stress of the mould, reducing thermal crack expansion risk by 75%. Annual comprehensive structural overhaul, surface polishing repair and performance testing can effectively extend mould service life by 30% and reduce long-term mould replacement cost.
