摘要: A method and apparatus are for coating a field joint of a pipeline. The method includes positioning a mold tool around the field joint to define a mold cavity, positioning an insert to lie within the mold cavity, and injecting plastics material into the mold cavity to embed the insert in the plastics material. The apparatus has a mold tool positionable around the field joint to define a mold cavity, and an insert positionable within the mold cavity to be embedded in plastics material injected into the mold cavity. Use of an insert in this way reduces the volume of the molten thermoplastics material required to coat the field joint, thereby increasing the interface area of the melt relative to its volume, to the benefit of cooling time.

摘要: A method for manufacturing a hollow plastic product. The method includes the steps of forming a reinforce member in a desired shape having a defined welding surface formed with a first hole by injection molding; forming a hollow main body by blow molding using said reinforce member as an insert, thereby having said reinforce member integrally formed with said hollow main body and having a portion of said hollow main body extended into said first hole in the shape of a mesa when blow-molded; thermally welding a top end surface of a connector pipe to said welding surface and also to a top surface of said mesa shaped portion; and forming a second hole in said top surface of said mesa shaped portion to be aligned with said second hole, thereby forming a fluidic communication passage between an interior of said hollow main body and an interior of said connector pipe.
摘要翻译: 一种中空塑料制品的制造方法。 该方法包括以下步骤:通过注射成型形成具有由第一孔形成的限定的焊接表面的期望形状的加强构件; 通过使用所述加强件作为插入件通过吹塑成型来形成中空主体,从而使所述加强件与所述中空主体一体形成,并且当所述中空主体的一部分在吹风时具有台面形状的所述第一孔延伸到所述第一孔中 模具 将连接管的顶端表面热焊接到所述焊接表面,并且还焊接到所述台面形部分的顶表面; 并且在所述台面形状部分的所述顶表面中形成与所述第二孔对准的第二孔,从而在所述中空主体的内部和所述连接管的内部之间形成流体连通通道。

摘要: THE PRESENT DISCLOSURE PERTAINS TO AN AUTOMATIC DRAIN TILE MAKING MACHINE WHICH EMPLOYS VERTICALLY RECIPROCAL PACKER HEADS AND PUSH-RODS TO FORM A TILE WITHIN A MOLD AND TO EJECT THE FORMED TILE ONTO A PALLET BY AXIALLY MOVING THE PUSH-RODS THROUGH THE MOLD. THE MACHINE IS PROVIDED WITH A PLURALITY OF MOLDS WHICH ARE FIXED TO A TURNTABLE SO AS TO PERMIT SIMULTANEOUS MOLDING AND EJEC-
TION DURING EACH VERTICAL CYCLE OF A HEAD WHCIH CARRIES THE PACKER HEADS AND PUSH-RODS.-
