Claim 15:
16. The production method according to claim 15, wherein in step 8, when the injection head injects the molten material into the locking cavities, 120-130 g of molten material is injected into the injection-molded locks of a single injection-molded floor blank; when the molten material passes through the nozzle to the straight flow channels, the molten material is injected at a pressure of 72-78 bar and a flow rate of 92-96% for a stroke of 58-65 mm; when the molten material passes through the straight flow channels to the curved flow channels, the molten material is delivered at a pressure of 28-32 bar and a flow rate of 68-72% for a stroke of 38-42 mm; when the molten material passes through the curved flow channels to the locking pin tubes, the molten material is delivered at a pressure of 15-21 bar and a flow rate of 48-52% for a stroke of 28-32 mm; and when the molten material passes through the locking pin tubes to the lock-shaped adhesive ports of the upper molding cavity, the molten material is delivered at a pressure of 52-58 bar for 0.13-0.17 s and at a flow rate of 48-52%.
