This custom injection mold is specially engineered for manufacturing semi-transparent PP plastic household small shovels. Adopting high-standard polished mold cavity design, it produces smooth, stain-resistant plastic shovels with integrated double-hole handle and large-capacity scoop body. The finished plastic shovel features seamless molding, easy cleaning, strong impact resistance, wide application in kitchen storage, pet feeding, grain handling and daily household sorting. Our mold supports multi-cavity customization, stable mass production and long service life for household plastic tool manufacturers.
2. Core Mold Advantages
High Gloss Polished Cavity
The mold inner cavity undergoes precision mirror polishing. The molded PP shovel surface is frosted semi-transparent without burrs, scratches or flow lines, eliminating secondary polishing procedures and improving finished product yield.
Stain-resistant Molding Solution
Matched with food-grade PP raw material molding parameters, the mold structural design avoids dead corners inside the shovel body. The produced plastic shovel is non-sticky to flour, feed, grains and powdery substances, easy to rinse and anti-stain for long-term use.
Durable Mold Base & Core
Adopts high-hardness mold steel for core and cavity, with anti-corrosion and anti-wear surface treatment. The mold can sustain hundreds of thousands of stable injection cycles, low maintenance frequency and long service lifespan.
Optimized Integrated Handle Structure
Precisely copies the double-layer hollow handle structure of the small shovel. One-step injection molding forms the handle and scoop body integrally, no assembly needed for finished shovels, greatly cutting post-production labor cost.
Balanced Injection Runner System
Customized runner and cooling channel layout ensures uniform filling of large shovel cavity. No shrinkage, deformation or warpage on the thin-wall plastic shovel, stable dimension tolerance for batch production.

FAQ
Q1: Can this mold produce colored plastic shovels besides semi-transparent white?
A1: Yes. The mold itself supports all color PP raw material injection; only color masterbatch needs to be adjusted during molding, no modification required on the mold structure.
Q2: Is the molded PP shovel food safe?
A2: The mold matches food-grade PP molding process parameters. If you use food contact certified PP pellets, the finished shovel fully meets kitchen food storage safety standards.
Q3: How long is the mold service life?
A3: Depends on mold steel. 718H steel supports up to 500,000 shots; 1.2344 hardened steel can reach 800,000 stable injection cycles with regular maintenance.
Q4: Can you adjust the shovel size via mold modification?
A4: We support size revision for new orders; minor size changes can be realized via core insert modification without re-opening the full mold, saving your cost.
Q5: Do you provide trial mold samples before shipment?
A5: Absolutely. We will complete trial injection, send physical PP shovel samples for your inspection, and adjust the mold until the finished product meets your requirements before packing and delivery.
