FAQ & Technical Considerations
Q1: How is warpage controlled for robot foot shells with nonuniform wall thickness?
Robot foot shells typically combine local reinforcing ribs, mounting bosses, and thin-wall sections in a single part, where uneven shrinkage during injection molding can cause warpage. Countermeasures include: CAE mold flow analysis during mold design to optimize gate placement and cooling circuit layout; selection of low-shrinkage glass fiber reinforced materials such as PA6GF30; and conformal cooling channels within the mold to improve cooling uniformity.
Q2: The foot shell contains metal inserts — how is insert positioning managed during injection molding?
Metal inserts (such as threaded brass inserts or sensor mounting plates) are located using prepositioned insert locating pins within the mold, and integrated with the plastic part through Insert Molding. For inserts with tight positional requirements, insert dimensional tolerances and mold locating mechanism geometry must be matched in the design stage to ensure insert position accuracy meets assembly requirements.
Q3: Robot housing programs often involve many part variants at low volumes — how can tooling costs be managed?
For multivariant, lowvolume robot housing development programs, the following approaches can be considered: multicavity tooling (e.g., 1×2 or 1×4 cavity) to increase output per shot; modular mold base design with interchangeable cavity inserts for geometrically similar parts to reduce repeated mold base investment; or simplified mold structures (cold runner, twoplate) for nonappearance parts to reduce initial tooling cost. Specific recommendations are provided based on part geometry and volume requirements.
Q4: Robot housing appearance surfaces have strict flatness requirements — how is this ensured in tooling?
Appearance surface flatness is influenced by mold cavity machining accuracy, steel hardness, and injection process parameters. We apply high-precision CNC machining and EDM to appearance part molds, achieving cavity surface roughness of Ra 0.4μm or below. During mold trials, process parameters are optimized to address any flatness deviation, with localized cavity polishing performed as needed until the appearance of the surface meets customer standards.
Q5: Is a one-stop service available from mold development through to assembled subassembly?
Yes. Our capabilities include injection molding, plastic welding (ultrasonic and hot plate), and component assembly. For multipart assembled structures such as robot foot shells, we can perform insert pressfitting, ultrasonic welding of subcomponents, and final assembly after injection molding, delivering near-complete assemblies to simplify supply chain management for the customer.
